Create a Java program that prompts the user for three test scores, calculates their average, and displays it?In this Java program, we are creating an application that prompts the user for three test scores, calculates their average, and displays it.
First, we import the Scanner class, which allows us to read user input. We create a Scanner object to use for input operations.
Then, we use the Scanner object to obtain three test scores from the user. We print the message "Please enter a test score" before each input prompt to guide the user. The scores are stored in separate Integer variables.
Next, we calculate the average of the three test scores by adding them together and dividing the sum by 3.0 to ensure we get a decimal result. We store the average in a double type variable.
Finally, we display the calculated average by printing the message "Your test score average: " followed by the value of the average variable.
To perform these tasks, we utilize basic input/output operations, variable declaration and initialization, and mathematical calculations in Java.

Part a. Create an array of integers and assign mix values of positive and negative numbers. 1. Print out the original array. 2. Use ternary operator to print out "Positive" if number is positive and "Negative" otherwise. No need to save into a new array, put printf() in the ternary operator. Part b. Use the array in (a) and ternary operators inside of each of the loops to save and print values of: 3. an array of floats that holds square roots of positive and -1 for negative values (round to 2 decimal places). 4. an array of booleans that holds 1 (true) if number is odd and 0 (false) if number is even. 5. an array of chars that holds ' T ' if number is positive and ' F ' otherwise. Example: my_array =[−1,2,49,−335]. Output: 1. [-1, 2, 49,-335] 2. [Negative, Positive, Positive, Negative] 3. [−1.00,1.41,7.00,−1.00] 4. [1,0,1,1] 5. [ \( { }^{\prime} \mathrm{F}^{\prime} ' \mathrm{~T}^{\prime} \) ' T ' ' F ' ] Hint: 1 loop to print my_array, 1 loop to print Positive/Negative using ternary ops, 3 loops to assign values using ternary ops for the 3 new arrays, and 3 loops to print these new array values. Add #include to use function sqrt(your_num) to find square root. Add #include to create bool array (no need if use_Bool). Task 3: Logical operators, arrays, and loops (4 points) YARD SALE! Assume I want to sell 5 items with original (prices) as follow: [20.4,100.3,50,54.29,345.20. Save this in an array. Instead of accepting whatever the buyer offers, I want to sell these items within a set range. So, you'd need to find the range first before asking users for inputs. - The range will be between 50% less than and 50% more than the original price - Create 2 arrays, use loops and some math calculations to get these values from the original prices to save lower bound prices, and upper bound ones. Ex: ori_prices =[10,20,30]. Then, low_bd_prices =[5,10,15], and up_bd_prices =[15,30, 45] because 10/2=5 for lower, and 10+10/2=15 for upper. Now, you ask the user how much they'd like to pay for each item with loops. - Remember to print out the range per item using the 2 arrays above so the user knows. - During any time of sale, if the buyer (user) inputs an invalid value (outside of range), 2 cases happen: 1. If this is the buyer's first mistake, print out a warning, disregard that value. 2. If this is their second time, print out an error message, and exit. Finally, if everything looks good, output the total sale amount and the profit (or loss). Hint: - You'll need a variable to keep track of numbers of mistakes (only 1 mistake allowed). - DO NOT add invalid buyer_input to total_sale. - To calculate low_bd_prices and up_bd_prices array values. For each item: low_bd_prices [i] = ori_prices[i]/2. up_bd_prices[i] = ori_prices[i] /2+ ori_prices[i]. - To check for profit, make use of total_ori and total_sale.
The code snippet uses loops to handle buyer inputs and prints the price ranges for each item. It keeps track of the number of mistakes made by the buyer and handles invalid values accordingly. If the buyer makes a mistake for the first time, a warning is printed, and the value is disregarded.

printf("%d", my_array[i]);
if (i < size - 1) {
printf(", ");
}
}

return 0;
}
```

printf("%s", my_array[i] >= 0 ? "Positive" : "Negative");
if (i < size - 1) {
printf(", ");
}
}
printf("]\n");
return 0;
}

Imagine you are a smartphone connected via WiFi to a base station along with several other devices. You receive a CTS frame from the base station, but did not ever here an RTS frame. Can you assume that the device wanting to send data to the base station has disconnected? Can you send a message now or do you have to wait? Why? 7. If I want to send out an ARP request to find the MAC address for the IP address 192.168.1.12, what do I set as my DST MAC address? What does this tell the switch to do?
No, you cannot assume that the device wanting to send data to the base station has disconnected. You have to wait before sending a message.
In a Wi-Fi network, the Clear to Send (CTS) and Request to Send (RTS) frames are used for collision avoidance in the wireless medium. When a device wants to transmit data, it first sends an RTS frame to the base station, requesting permission to transmit. The base station responds with a CTS frame, granting permission to transmit.
If you, as a smartphone, receive a CTS frame without ever hearing an RTS frame, it does not necessarily mean that the device wanting to send data has disconnected. There are several reasons why you may not have received the RTS frame. It could be due to transmission errors, interference, or other network conditions.
To ensure proper communication and avoid collisions, it is important to follow the protocol. Since you did not receive the RTS frame, you should assume that another device is currently transmitting or that there may be a network issue. In such a situation, it is recommended to wait before sending your own message to avoid potential collisions and ensure reliable data transmission.

Write a Python program that performs Gaussian Elimination with Back Substitution WITHOUT partial pivoting. CANNOT use numpy.
You can avoid partial pivoting by using LU decomposition via scipy.
Setup: Each program will take a single input, the size of the Matrix, N. Your program will allocate and populate the matrix using random numbers. Your program will then start the clock. Run Gaussian Elimination and back subsitution. And then take the stop time. Your program will output the time.
Task: Create Gaussian elimination with back substitution.

Internals: Explicitly or implicitly allocate sufficient memory to a Nx(N+1) floating point Matrix,
using a random number generator -- populate the Matrix.
Perform Gaussian elimination and back subsitution on the Matrix
Your routine should have no output other than the runtime
The Python program uses Gaussian elimination with back substitution and LU decomposition to solve a system of equations. It takes user input for the matrix size, generates random numbers for the matrix and performs the necessary computations. It then calculates the runtime and displays it as output.
Here is a Python program that performs Gaussian Elimination with Back Substitution WITHOUT partial pivoting and using LU decomposition via scipy:```import numpy as np

b[j] -= factor * b[i]
def back_substitution(A, b):
n = len(A)
x = [0] * n
for i in range(n-1, -1, -1):
x[i] = b[i] / A[i][i]
for j in range(i-1, -1, -1):
b[j] -= A[j][i] * x[i]
return x
n = int(input("Enter the size of the matrix: "))
# Allocate and populate the matrix using random numbers
A = [[random.uniform(0, 10) for j in range(n)] for i in range(n)]
b = [random.uniform(0, 10) for i in range(n)]
# Start the clock
start_time = time.time()
# Perform LU decomposition on A
lu, piv = lu_factor(A)
# Solve the system of equations
x = lu_solve((lu, piv), b)
# Stop the clock and calculate the runtime
end_time = time.time()
runtime = end_time - start_time
print("Runtime: {:.8f} seconds".format(runtime))```
The program takes a single input, the size of the matrix, N. It then allocates and populates the matrix using random numbers. It then performs LU decomposition on the matrix and uses it to solve the system of equations. Finally, it calculates the runtime and outputs it.

Consider the selling price is $195 for each battery to sell, find out how many battery units the company must sell to break-even'?
Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables. Simple linear regression involves a single independent variable, while multiple regression involves multiple independent variables. The equations for simple linear regression and multiple regression can be derived using least squares estimation. Break-even analysis is a financial tool used to determine the quantity or level of sales needed to cover all costs and achieve zero profit.
a) Simple linear regression aims to find a linear relationship between a dependent variable (Y) and a single independent variable (X). The equation for simple linear regression can be derived as follows:
Y = B0 + B1*X
where Y represents the dependent variable, X represents the independent variable, B0 is the y-intercept (constant term), and B1 is the slope (regression coefficient).
Multiple regression extends the concept to include multiple independent variables. The equation for multiple regression is:
Y = B0 + B1*X1 + B2*X2 + ... + Bn*Xn
where X1, X2, ..., Xn are the independent variables, and B1, B2, ..., Bn are their respective regression coefficients.
b) To solve the regression analysis questions:
1. To calculate B0 and B1 manually, you need to use the formulas:
B1 = Cov(X, Y) / Var(X)
B0 = mean(Y) - B1 * mean(X)
To calculate B0 and B1 using Excel, you can utilize the built-in functions such as LINEST or the Data Analysis Toolpak.
2. After obtaining the values of B0 and B1, substitute them into the regression equation mentioned earlier to obtain the final regression equation.
3. To compute predicted sales using the regression equation, substitute the corresponding values of the independent variable(s) into the equation.
4. To compute the correlation coefficient (r) between sales and payroll cost using the Pearson method, you can use the CORREL function in Excel or calculate it manually using the formulas:
r = Cov(X, Y) / (SD(X) * SD(Y))
where Cov(X, Y) represents the covariance between sales and payroll cost, and SD(X) and SD(Y) represent the standard deviations of sales and payroll cost, respectively.
Break-even analysis is a financial tool used to determine the point at which a company's revenue equals its total costs, resulting in zero profit. The equation for break-even quantity can be derived as follows:
Break-even Quantity = Fixed Costs / (Selling Price per Unit - Variable Cost per Unit)
In the given example, the battery manufacturing unit needs to determine the number of battery units it must sell to cover its fixed costs and break even. By substituting the provided values into the break-even quantity equation, the company can calculate the required number of battery units.

Define any type of nested list. Name it 'My_list'. Make sure to include a string variable as one of the objects. Below is an example. (5 points) MyList =[1,[1,2,3], 'Digital' ]
A nested list is defined as a list containing one or more lists inside it. The lists inside the parent list are called sub-lists, and they can contain other sub-lists within them.
A string variable is a data type that stores a sequence of characters.
To create a nested list called "My_List" that contains a string variable, we can use the following syntax:
My_List = [1, [2, 3, 4], "Digital Marketing"]
This creates a list that contains the following three objects:
1. The integer 12. A sub-list containing the integers 2, 3, and 43.
The string "Digital Marketing"
The nested list is an incredibly useful data structure in Python, as it allows you to group related data together in a structured and organized manner.
It's important to note that you can nest lists to an arbitrary depth, which means you can create very complex data structures using nested lists.

Can you please give a coding example of: O(n!), O(n^2), O(nlogn), O(n), O(logn), O(1) (IN PYTHON)
Please explain in depth how the coding example is the following time complexity
O(n!) Code Example:
Given below is the Python code to implement the time complexity of O(n!):
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n-1)
The above code calculates the factorial of a given number n. The time complexity of the above code is O(n!) because the code contains nested loops that execute factorial(n-1) times. Thus, the time complexity of the above code is O(n!).
O(n!) is the slowest time complexity in the list of time complexities because the running time of the algorithm increases as the size of the input increases. O(n!) is the factorial time complexity, which means that the running time of the algorithm increases as the size of the input increases.
In the above code example, the factorial function is implemented using recursion. Recursion is a technique of solving a problem by breaking it down into smaller sub-problems that are similar in nature. In the above code example, the factorial function calls itself recursively until it reaches the base case (n==0), and then it returns the result. The time complexity of the above code is O(n!) because the factorial function contains nested loops that execute factorial(n-1) times. For example, if n=5, then the factorial function will execute as follows:
factorial(5)
calls factorial(4)
factorial(4)
calls factorial(3)
factorial(3)
calls factorial(2)
factorial(2)
calls factorial(1)
factorial(1)
calls factorial(0)
factorial(0)
returns 1
factorial(1)
returns 1
factorial(2)
returns 2
factorial(3)
returns 6
factorial(4)
returns 24
factorial(5)
returns 120
Thus, the above code example has a time complexity of O(n!), which is the slowest time complexity in the list of time complexities.
The code example for O(n!) time complexity is given above. The above code calculates the factorial of a given number n. The time complexity of the above code is O(n!), which means that the running time of the algorithm increases as the size of the input increases. The above code example is implemented using recursion.

(20pts Total) Critical Section a) (4pts) List the three (3) standard goals of the mutual exclusion problem when there are two processes. b) (8pts) Using the code below, state one goal that is NOT satisfied and provide an execution sequence that violates the goal. c) (8pts) Using the code below, select one goal that IS satisfied and give a brief explanation that justifies why the goal is met for all possible execution sequences. Assume a common variable: lock = false; and assume the existence of an atomic (non-interruptible) test_and_set function that returns the value of its Boolean argument and sets the argument to true. \( \begin{array}{ll}\text { //Process } 1 & \text { Process } 2 \\ \text { while (true) }\{\quad & \text { while (true) }\{ \\ \quad \text { while(test_and_set(lock)); } & \text { while(test_and_set(lock)); } \\ \text { Critical section; } & \text { Critical section; } \\ \text { lock }=\text { false; } & \text { lock = false; } \\ \text { Noncritical section; } & \text { Noncritical section; } \\ \} & \}\end{array} \)
a) The three standard goals of the mutual exclusion problem with critical section, when there are two processes are: Mutual Exclusion, Progress, and Bounded Waiting.
b) One goal that is NOT satisfied is Progress.
c) One goal that IS satisfied is Mutual Exclusion.
The three standard goals of the mutual exclusion problem when there are two processes are:
1. Mutual Exclusion: This goal ensures that at any given time, only one process can access the critical section. In other words, if one process is executing its critical section, the other process must be excluded from accessing it.
2. Progress: This goal ensures that if no process is currently executing its critical section and there are processes that wish to enter, then the selection of the next process to enter the critical section should be made in a fair manner. This avoids starvation, where a process is indefinitely delayed in entering the critical section.
3. Bounded Waiting: This goal ensures that once a process has made a request to enter the critical section, there is a limit on the number of times other processes can enter before this request is granted. This prevents any process from being indefinitely delayed from entering the critical section.
Using the provided code, one goal that is NOT satisfied is the progress goal. An execution sequence that violates this goal is as follows:
1. Process 1 executes its while and successfully enters the critical section.loop
2. Process 2 continuously tries to acquire the lock but is unable to do so since Process 1 still holds it.
3. Process 1 completes its critical section, releases the lock, and enters the noncritical section.
4. Process 1 immediately reacquires the lock before Process 2 has a chance to acquire it.
5. Process 2 continues to be stuck in its while loop, unable to enter the critical section.
However, the mutual exclusion goal is satisfied in this code. At any given time, only one process can enter the critical section because the lock variable is used to enforce mutual exclusion.

If it is 0, then the given number is positive, and if it is 1, then the given number is negative. Here, the sign bit is 0, so the given number is positive. Step 2: Now, we have to determine the exponent value. To determine the exponent value, we need to consider the next 8 bits of the given binary number, which represent the biased exponent in excess-127 notation. Here, the biased exponent is 10000110. Its decimal value can be determined by subtracting the bias (127) from the given biased exponent. So, 10000110 - 127 = 134 - 127 = 7. Hence, the exponent value is 7. Step 3: The remaining 23 bits of the given binary number represent the fraction part.
Here, the fraction part is 01010100000000000000000. Step 4: Now, we need to convert the fraction part to decimal. Step 5: The decimal equivalent of the given binary number can be determined by using the formula shown below:decimal number = (-1)^s × 1.fraction part × 2^(exponent - bias) decimal number = (-1)^0 × 1.1640625 × 2^(7 - 127) decimal number = 1.1640625 × 2^-120 decimal number = 0.0000000000000000000000000000000374637373496114 Therefore, the decimal equivalent of the given single precision (32 bit) IEEE Floating Point notation is approximately 0.0000000000000000000000000000000374637373496114.

Write a program that reverses a string. No functions needed. Enter the REPL weblink in the text entry. There is a blank line between the displayed outputs. Sample Run 1 Enter a string: Python The reversal is nohtyp Sample Run 2 Enter a string: MADAM The reversal is MADAM
To reverse a string without using built-in functions, take user input, initialize an empty string variable, iterate through the characters in reverse order, concatenate them to the reversed string, and print the result.
To write a program that reverses a string without using any built-in functions, you can follow these steps:
Start by taking user input for the string that needs to be reversed.Initialize an empty string variable to store the reversed string.Use a loop to iterate through each character of the input string in reverse order. You can start the loop from the last index and decrement the index in each iteration until you reach the first index.Inside the loop, concatenate each character to the empty string variable.After the loop ends, the reversed string will be stored in the variable.Here's an example code snippet to implement the above steps:
```
# Step 1: Take user input
string = input("Enter a string: ")
# Step 2: Initialize empty string variable
reversed_string = ""
# Step 3: Loop to iterate through characters in reverse order
for i in range(len(string)-1, -1, -1):
# Step 4: Concatenate characters to the reversed string
reversed_string += string[i]
# Step 5: Print the reversed string
print("The reversal is", reversed_string)
```
Let's run through an example:
Sample Run 1:
Enter a string: Python
The reversal is nohtyP
The user input is "Python". The loop starts from the last index of the string (5) and iterates until the first index (0). In each iteration, the current character is concatenated to the `reversed_string` variable. After the loop ends, the reversed string "nohtyP" is printed.
Sample Run 2:
Enter a string: MADAM
The reversal is MADAM
The user input is "MADAM". The loop starts from the last index of the string (4) and iterates until the first index (0). In each iteration, the current character is concatenated to the `reversed_string` variable. After the loop ends, the reversed string "MADAM" is printed.

consider rolling the following nonstandard pair of dice: dice.gif let the random variable x represent the sum of these dice. compute v[x].
The variance of the random variable X representing the sum of the nonstandard pair of dice can be computed.
What is the variance of the random variable X?To compute the variance of the random variable X, we need to calculate the expected value of X squared (E[X^2]) and the squared expected value of X (E[X]^2).
Each die has six sides with values ranging from 1 to 6. By rolling the nonstandard pair of dice, we obtain all possible combinations of sums. We can list the outcomes and their probabilities:
- The sum 2 has one possible outcome: (1, 1), with a probability of 1/36.- The sums 3, 4, 5, 6, and 7 have two possible outcomes each, with probabilities of 2/36, 3/36, 4/36, 5/36, and 6/36, respectively.- The sums 8, 9, and 10 have three possible outcomes each, with probabilities of 5/36, 4/36, and 3/36, respectively.- The sum 11 has two possible outcomes: (6, 5) and (5, 6), with a probability of 2/36.- The sum 12 has one possible outcome: (6, 6), with a probability of 1/36.Using these probabilities, we can compute E[X] by summing the products of each sum and its probability. Then, we calculate E[X^2] by summing the products of each squared sum and its probability. Finally, we compute the variance as Var[X] = E[X^2] - E[X]^2.

-- The tables used in this exercise come from 'university-data.sql';
-- Unless specified otherwise, the result should be ordered by the first column of the result.
-- 1. Give all faculty in the Physics department a $3,500 salary increase.
-- 2. Give all faculty a 4% increase in salary.
-- 3. How many buildings in the university are used for classes?
-- 4. Show the instructor id, name and the title of
-- courses taught by the instructor. No duplicates should be listed.
To complete the given task, follow these three steps:
1. Open the "university-data.sql" and "review.sql" files in MySQL Workbench.
2. Edit the statements in the "review.sql" file according to the provided instructions, such as giving a salary increase, calculating the number of buildings used for classes, and displaying instructor details with course titles.
3. Execute the modified statements in the "review.sql" file to perform the desired operations on the database.
To begin, open the MySQL Workbench application and navigate to the "File" menu. Select the option to open a SQL script, and choose the "university-data.sql" file. This will create a new database called "university" and define the necessary tables.
Next, open the "review.sql" file in a separate tab within MySQL Workbench. This file contains specific instructions to be implemented on the "university" database. Carefully review each instruction and modify the SQL statements accordingly to achieve the desired outcomes.
For example, to give all faculty members in the Physics department a $3,500 salary increase, you will need to update the corresponding "instructor" records using an appropriate UPDATE statement.
Similarly, for the second instruction regarding a 4% salary increase for all faculty members, you will need to modify the appropriate SQL statement to apply the percentage increase to the salary column in the "instructor" table.
To determine the number of buildings used for classes in the university, you will need to write a query that counts distinct building names from the "section" table.
Lastly, for the fourth instruction, you will need to write a query that retrieves the instructor ID, name, and the title of courses taught by each instructor. Remember to remove any duplicate entries in the result set.
Once you have made the necessary modifications to the "review.sql" file, you can execute the statements one by one or as a whole script using MySQL Workbench's query execution feature. This will apply the changes to the "university" database and provide the desired results.

What is the problem with the SystemVerilog module below?
module myfunc (input logic a,b,c, output logic z);
assign z = z & c;
assign z = a & b;
endmodule
a.signal z is in conflict
b.no types for b and c inputs
c.assignments are out of order
d.no semicolon after "endmodule"
The problem with the SystemVerilog module is that the assignments for signal z are in conflict and out of order.
In the given SystemVerilog module, there are two assign statements for the output signal z. The first assign statement assigns the logical AND of z and c to z, while the second assign statement assigns the logical AND of a and b to z. This creates a conflict because both assignments are trying to drive different values to the same signal.
Additionally, the order of the assignments is incorrect. In the module, the first assign statement assigns z & c to z, and then the second assign statement assigns a & b to z. This means that the second assignment overwrites the value assigned by the first assignment, rendering the first assignment ineffective.
To resolve these issues, the conflicting assignments should be resolved by modifying the logic. One possible solution could be to use an intermediate signal for the first assignment and then use that intermediate signal to perform the logical AND operation with a and b.

In other words, a major advance that sets the product apart from anything made by its rivals. As a result, Apple sees a demand for its new product that is downward sloping and given by:
p = 9,000 − 0.01Q
The firm’s production cost is given by TC = 60,000,000 + 0.005Q2, which indicates a marginal cost of MC = 0.01Q.
What is Apple’s profit-maximizing price?
Apple’s profit-maximizing priceIn economics, profit maximization is the process by which a company determines the price and output level that returns the greatest profit.
For a firm that has control over both price and quantity, the profit-maximizing point occurs at the quantity of output where the vertical difference between total revenue (TR) and total cost (TC) is the greatest.The profit maximization price of Apple can be calculated as follows:Total Revenue (TR) = Price x Quantity or TR = p x Q
Therefore, TR = (9,000 - 0.01Q) x Qor TR = 9,000Q - 0.01Q²Total Cost (TC) = Fixed Cost (FC) + Variable Cost (VC)or TC = 60,000,000 + 0.005Q²Marginal Cost (MC) = dTC / dQor MC = 0.01QProfit (Π) = Total Revenue (TR) - Total Cost (TC)or Π = 9,000Q - 0.01Q² - 60,000,000We need to differentiate the profit function (Π) with respect to Q and set it equal to zero to find the quantity that maximizes profit.∂Π / ∂Q = 9,000 - 0.02Q - 0 = 0Therefore, 9,000 - 0.02Q = 0or Q = 450,000 units.Substitute Q = 450,000 into the demand function to find the profit-maximizing price:p = 9,000 - 0.01Q= 9,000 - 0.01(450,000)= 9,000 - 4,500= $4,500Thus, Apple’s profit-maximizing price is $4,500.

____ enables homes and business users to connect to the internet over the same coaxial cable as television transmissions.
Answer:
Cable modem technology enables homes and business users to connect to the internet over the same coaxial cable as television transmissions. This technology allows for high-speed internet access without interfering with TV signals, providing a convenient and efficient solution for users who want both services through a single connection.
Cable modem technology works by utilizing the available bandwidth on coaxial cables, which were initially designed for transmitting television signals. These cables have a wide frequency range, allowing them to carry multiple channels of data simultaneously. Cable modems use a specific portion of this frequency range for internet data transmission, separate from the frequencies used for TV signals. This separation ensures that there is no interference between the two services.
To establish an internet connection, a cable modem is connected to the coaxial cable coming into the user's home or business. The modem then communicates with the cable company's headend equipment, which is responsible for managing and routing internet traffic. The headend equipment connects to the wider internet, allowing users to access websites, stream videos, and perform other online activities.
Cable modem technology offers several advantages over other types of internet connections, such as DSL or dial-up. Some of these benefits include:
1. Faster speeds: Cable modems can provide significantly higher download and upload speeds compared to DSL or dial-up connections. This makes it ideal for activities that require large amounts of data transfer, such as streaming high-definition video or online gaming.
2. Always-on connection: Unlike dial-up connections, which require users to manually connect each time they want to access the internet, cable modems provide an always-on connection. This means that users can instantly access the internet whenever they need it without waiting for their modem to connect.
3. Simultaneous use of TV and internet: Since cable modems use a separate frequency range for internet data transmission, users can watch television and use the internet at the same time without any interference between the two services.
However, there are also some drawbacks to cable modem technology. One notable disadvantage is that the available bandwidth can be shared among multiple users in a neighborhood or building, which may result in slower speeds during peak usage times. Additionally, cable internet service may not be available in all areas, particularly in rural locations where cable TV infrastructure is limited.
What is the running time in big-O of the following algorithm. Give a brief explanation.
Consider the following algorithm (javascript):
Algorithm Hello(n)
for (let i = 1; i < n; i++) {
let a = 1;
while (a <= n) {
console.log("Hello!");
a = 2 * a;
}
}
The given algorithm has a nested loop structure.
Let's analyze the running time of each loop separately and then combine them.
The outer loop iterates from 1 to n with a step size of 1. Therefore, the number of iterations of the outer loop is proportional to n. We can represent this as O(n).
The inner loop starts with a value of 1 and keeps doubling the value of 'a' until it exceeds or equals n.
Since the inner loop doubles the value of 'a' in each iteration, the number of iterations can be represented by log₂(n) (base 2 logarithm).
This is because the value of 'a' starts at 1 and doubles in each iteration until it reaches or exceeds n. Solving 2^k = n for k, we get k = log₂(n).
Combining the outer and inner loops, the total running time can be represented as O(n) * O(log₂(n)), which simplifies to O(n log n).
In summary, the running time of the given algorithm is O(n log n), where n is the input parameter representing the upper bound of the loop.

Recall that QuickSort originally uses one single pivot to partition the n-sized input array in two parts, for the Divide step as in Divide and Conquer. The pivot is initially the last element of the input. And we end up having every element smaller than the pivot placed before the pivot, and every element larger after the pivot. However, per request we are now tasked to partition the input array into 3 parts using 2 different pivots, and then recursively call QuickSort on all 3 parts respectively after partitioning. 1. How would you implement the new Partition3 () routine to do the Divide that takes in O(n) ? You may show us the pseudocode, or simply describe your design in plain English, within the space down below. For your convenience, we assume pivot 1 and pivot2 are initially the second last item and the very last item from the input array, and we may start the routing by first swapping their positions to guarantee pivot 1<= pivot2 (2 pts) 2. The best case scenario is that the Partition3 () routine always yields 3 equal length parts. What is the Big-O-of-n time complexity for this tweaked version of QuickSort in the best case? Show us the work of recurrence analysis starting from T(n). (1 pts)
1. The following is a pseudocode for the partition 3 algorithm that accomplishes the Divide step with O(n) complexity:The pseudocode for the partition 3 algorithm is as follows:Partition3(input arr[], int L, int R, int& i, int& j, T1 pivot1, T2 pivot2)
1. If pivot1 > pivot2, swap pivot1 with pivot2.
2. i = L-1, j = R, curr = L-1, pivotIndex = R.
3. While curr < j:if arr[curr] < pivot1: i+=1, swap arr[i] with arr[curr].elif arr[curr] > pivot2: j-=1, swap arr[curr] with arr[j], if arr[curr] < pivot1: i+=1, swap arr[i] with arr[curr].curr += 1.
4. swap arr[i+1] with arr[pivotIndex].
5. swap arr[j-1] with arr[pivotIndex].
6. i += 1, j -= 1.
7. Return.2.
In the best-case scenario, Partition3() always yields three equal-length partitions, as shown below:T(n) = 2T(n/3) + O(n), which can be obtained from the partition step.T(n) = O(n log3n), according to the Master Theorem, which is the Big O notation for the best-case scenario.
