Below is the solution to the Python program that prompts the user to enter two integer numbers A and B, which checks whether the sum of the numbers is equal to the second power of either A or B. The user is allowed to enter two numbers for 5 times maximum. When the sum is equal to the second power of either x or y, the program outputs the sum and the number of tries. It also outputs "The numbers should be positive!" when either x or y is negative.
```python
def check_sum_power(x, y):
for i in range(5):
a = int(input("Enter two integers: ").strip())
b = int(input().strip())
if a < 0 or b < 0:
print("The numbers should be positive!")
elif a+b == x**2:
print("The numbers are {} and {}, their sum is {}. The number of tries is {}.".format(a, b, x**2, i+1))
return
elif a+b == y**2:
print("The numbers are {} and {}, their sum is {}. The number of tries is {}.".format(a, b, y**2, i+1))
return
print("Max attempts reached!")
x = int(input().strip())
y = int(input().strip())
check_sum_power(x, y)
```
In the above program, the function `check_sum_power` takes two integer arguments, `x` and `y`. It prompts the user to enter two integer numbers for 5 times maximum. When the sum of the numbers is equal to the second power of either `x` or `y`, it prints the sum and the number of tries. It also prints "The numbers should be positive!" when either `x` or `y` is negative.
The function `check_sum_power` is called by passing two integer values `x` and `y` as input to the program. The function calls `input()` method to get the input from the user. It then checks whether the sum of the two numbers is equal to the second power of either `x` or `y`. If the sum is equal to the second power of either `x` or `y`, it prints the output and returns from the function. Otherwise, it continues the loop for the maximum number of tries. If the maximum number of tries is reached and the sum is not found, it prints "Max attempts reached!" and exits the function.

In two or three paragraphs, in your own words, explain how vital the minimal or load provisions are to structural design or structure in general.
Structural design has several components that work together to produce a sturdy and functional framework for a building or structure. The minimum or load requirements are critical to ensuring that a building can support the loads it is meant to bear. Here is an explanation of how vital minimal or load provisions are to structural design or structure in general:
AnswerThe building's overall weight, as well as the weight of the occupants, furnishings, and other objects, must be considered when determining the minimum or load requirements. The structure should also be able to withstand the forces generated by natural phenomena like earthquakes, hurricanes, and windstorms, which are beyond human control. A building that meets the minimum or load requirements is more likely to survive an earthquake or windstorm than one that does not.Life safety is a critical concern in structural design. Load provisions assist in creating a safe structure for individuals and property, ensuring that they are protected in the event of a disaster. To ensure a sturdy structure, engineers and architects must be skilled in determining and interpreting load provisions. Structural design is not only concerned with the physical characteristics of a building, but it must also meet local building codes and regulations to ensure that it is safe to use and inhabit. The construction materials, the size of the building, and other factors are all considered when creating a building or structure that is safe and secure.The load provision is essential to the structural design of any building.
A building that meets the minimum or load requirements is more likely to survive an earthquake or windstorm than one that does not. To ensure that a building is structurally sound and meets all regulatory and safety requirements, engineers and architects must be skilled in determining and interpreting load provisions. An accurate understanding of the load provisions ensures that the structure will withstand the weight of the occupants, furnishings, and other objects, as well as any natural phenomena like hurricanes, earthquakes, or windstorms that may arise. Therefore, load provisions play a crucial role in structural design and are necessary for the safety of any building.

Refer to the previous problem. Calculate the resulting maximum positive moment (kN-m). 0 77.4 O 96.8 O 54.4 108.8 SITUATION. A simply supported beam has a span of 12 m. It carries a total uniformly distributed load of 21.5 kN/m. To prevent excessive deflection, a support is added at midspan. Calculate the reaction (kN) at the added support. 96.75 O 161.25 80.62 48.38
Given Data:The span of the simply supported beam = 12 m,Total uniformly distributed load of the beam = 21.5 kN/mWe are to calculate the maximum positive moment (kN-m) of the simply supported beam and the reaction (kN) at the added support.
Solution:To find the maximum positive moment of the simply supported beam:
Maximum bending moment occurs at mid-span of the beam where the load is maximum and the slope of the beam is zero.Let 'x' be the distance of the mid-span from the left support.
So, the distance of the mid-span from the right support = (12 - x)Total uniformly distributed load on the beam
= 21.5 kN/m
Maximum bending moment at the mid-span of the beam = wl² / 8 ... (1)
Here, w = Total uniformly distributed load on the beam = 21.5 kN/mSo, the bending moment at the mid-span of the beam can be given by:
Maximum bending moment = (21.5 × x²) / 8
= (2.6875x²) kN-m ... (2
)Also, the reaction at both ends of the simply supported beam is equal to half of the total load.So, the reaction at each end of the beam = (1/2) × 21.5 × 12 = 129 kN
The reaction at the mid-span of the beam is equal to the support added to prevent excessive deflection.So, the reaction at the added support = 129 kN
Therefore, the resulting maximum positive moment is 54.4 kN-m. Hence, the correct option is O 54.4The reaction at the added support is 96.75 kN.
Hence, the correct option is 96.75.

The minimum pressure on an object moving horizontally in water (Ttemperatu at10 degree centrigrade) at 22 mm/s at a depth of 1 m is 80 kPa (absolute). Calculate the velocity that will initiate cavitation
Cavitation is a phenomenon that occurs when the pressure of a liquid becomes less than its vapor pressure at a specific temperature. When cavitation takes place, bubbles form, and as the pressure increases, the bubbles collapse, creating tiny shock waves. The collapse of these bubbles causes damage to nearby surfaces, resulting in decreased efficiency and equipment wear and tear.
To determine the velocity at which cavitation will occur, the Bernoulli equation may be used. Bernoulli's equation is used to describe the relationship between the velocity of a fluid, its pressure, and its elevation above a reference point. In a horizontal pipe, the equation is given as follows:P1 + ρ * v12/2 = P2 + ρ * v22/2where P1 and P2 are the pressure at points 1 and 2, respectively. ρ is the density of the fluid, and v1 and v2 are the velocity of the fluid at points 1 and 2, respectively. In this instance, point 1 is at a depth of 1 m, and point 2 is at the surface of the water, where the pressure is atmospheric.To calculate the velocity that will initiate cavitation, we must first determine the pressure at point 2.P1 + ρ * v12/2 = P2 + ρ * v22/2Rearranging, we get:P2 = P1 - ρ * (v22 - v12)/2At 1 m depth in water at a temperature of 10°C, the absolute pressure is:P1 = 80 kPa + 101.325 kPa = 181.325 kPaAt the surface, where P2 is atmospheric pressure, we have:P2 = 101.325 kPaSubstituting these values into the equation:P2 = P1 - ρ * (v22 - v12)/2Solving for v2:v2 = sqrt(2*(P1 - P2)/ρ)The density of water at 10°C is approximately 999 kg/m³, which is used to solve for v2.v2 = sqrt(2*(181.325 kPa - 101.325 kPa)/(999 kg/m³))= 7.27 m/sTherefore, a velocity greater than 7.27 m/s at a depth of 1 m in water at 10°C would result in cavitation.

Compare and contrast lists, dictionaries, and sets in Python. What do they have in common? What is different? Which are ordered vs unordered? What types of objects can they contain? Can they contain multiple copies of the same object?
Lists, dictionaries, and sets are data structures in Python programming that are used to store collections of data. In this context, this answer shall compare and contrast the three.
Lists are ordered and mutable sequences of elements, meaning that the position of elements in a list matters.
They can contain duplicate elements, and multiple copies of the same object are permitted. Lists are defined by square brackets([]) and are separated by commas. They can store a variety of objects, including other lists, tuples, strings, integers, and even other functions.
Dictionaries are unordered and mutable collections of key-value pairs. Dictionaries are defined by a curly bracket({}) and separated by commas. The key-value pairs can have different data types. Dictionaries cannot contain duplicate keys, but values can be duplicated. They can contain lists, other dictionaries, integers, strings, and tuples.
Sets are mutable and unordered collections of unique elements, meaning they contain no duplicates. Sets are defined by curly brackets({}) and are separated by commas. They contain simple data types such as strings, integers, and floats.

The given code snippet is written in C/C++. The program consists of two for loops nested inside each other, and several conditional statements and assignments. The outer loop is used to iterate over the values of the variable i from 1 to n, incrementing i by 3 at each iteration.
The inner loop iterates over the values of j from 1 to n, incrementing j by 1 at each iteration. Here is a detailed explanation of the code:```
for (int i = 1; i <= n; i+=3) {
for (int j=1; j <= n; j++) {
if (j % 3 == 0) {
// 4 assignments
}
if (2*1 + 3 == 5) {
// 17 assignments
}
}
}
```In the above code, the outer for loop starts with initializing the value of i to 1 and checks if the value of i is less than or equal to n. It then increments the value of i by 3 in each iteration. The inner for loop initializes the value of j to 1 and checks if the value of j is less than or equal to n. It then increments the value of j by 1 in each iteration.The first conditional statement inside the inner loop checks if the value of j is divisible by 3. If the value of j is divisible by 3, then the code inside the if block executes. In this case, there are 4 assignments made inside the if block, which are not shown in the given code snippet.The second conditional statement inside the inner loop checks if the expression 2*1 + 3 is equal to 5. Since the expression evaluates to true, the code inside the if block executes. In this case, there are 17 assignments made inside the if block, which are not shown in the given code snippet.In summary, the given code snippet executes two nested for loops, with the outer loop incrementing i by 3 in each iteration and the inner loop incrementing j by 1 in each iteration. The first conditional statement inside the inner loop executes if j is divisible by 3 and makes 4 assignments, while the second conditional statement inside the inner loop executes if the expression 2*1 + 3 is equal to 5 and makes 17 assignments.

(1) Is it possible that both processes are trapped in lock() (which means the while loop condition is true and thus looping at the while loop) at the same time and thus none of them can enter the critical section? Why? (4 marks) (2) When the two processes finish execution, is it possible that the value of ans is smaller than 20? Why? (4 marks) (3) If PO and P1 start execution at the same time, is it possible that PO executes ans++ for multiple times before Pl executes ans++ for the first time? Why? (4 marks) (4) If PO and P1 are executing on the same CPU core, is there any disadvantage to implement the lock/unlock function pair as shown in the question? If yes, what are the approaches to address this kind of disadvantage?
(1) It is possible that both processes are trapped in lock () at the same time because the turn variable will be changed to 1 - self, which is the other process, and the while loop will never return because flag [1 - self] is still set to true. Thus, the while loop condition is still true.
Hence, both processes will wait in the lock () function indefinitely, preventing them from entering the critical section.(2) Yes, it is possible that the value of ans is less than 20 because the critical section is not protected by the lock () function. As a result, both processes can update the value of ans at the same time, causing a race condition where only one process’s update of ans is taken into account while the other’s update is lost.
This is possible because both processes are working on different locks and can enter their critical sections independently of one another. As a result, PO can enter and execute the critical section multiple times before P1 is given the chance to enter it, resulting in PO updating the value of ans multiple times before P1 updates it.(4) If PO and P1 are executing on the same CPU core, there is a disadvantage to implementing the lock/unlock function pair as shown in the question.

What causes the extraordinarily fast voltage drop with increasing load in a de compound generator?
The main reason for the extraordinarily fast voltage drop with increasing load in a de compound generator is caused by the low resistance of the series field winding, which tends to cause a high current to flow through it when the load on the generator increases.
What is a compound generator? A compound generator, also known as a compound motor, is a DC generator in which the shunt field winding is connected in series with the armature winding to produce a magnetic field that helps boost the generator's voltage. Compound generators are designed to be self-regulating in voltage, but their voltage regulation is not as good as that of separately excited DC generators.
Why does voltage drop occur? When the load on a generator increases, the generator's armature current also increases, resulting in an increase in the magnetic flux density in the series field winding. As a result, a higher voltage is produced across the series field winding's terminals, causing the voltage at the generator's output terminals to drop. As a result, the terminal voltage on a compound generator decreases much more rapidly than on a shunt generator, which causes voltage regulation to suffer.

Code fragment 1 has a Big-O of O(n). Code fragment 2 has a Big-O of O(n^2). Code fragment 3 has a Big-O of O(n log n).
The Big-O notation expresses the upper bound on the number of operations for a given algorithm in terms of the input size n. The time complexity of code fragment 1 is O(n) because the loop runs n/2 times, and therefore, it is O(n).The time complexity of code fragment 2 is O(n^2) because there are two nested loops. The outer loop executes n times, while the inner loop executes n-1 times, so the total time complexity is O(n^2).
The time complexity of code fragment 3 is O(n log n) because the outer loop executes log n times, and the inner loop executes j times on each iteration, which is half of the previous iteration's value. As a result, the time complexity is O(n log n).

The efficiency of the turbine is n = 25%, meaning that 25% of the kinetic energy in the wind can be extracted. Calculate the power in watts that can be produced by your turbine.
The power produced by the turbine is 153994.8 watts
The formula for calculating the power generated by a wind turbine is:P = (1/2)ρA v³ nWhere:P = Power, in wattsρ = Density of air, in kg/m³A = Swept area of the blades, in m²v = Velocity of wind,
in m/sn = Efficiency of the turbineGiven that: x = 75D = x + 1.25 ft,
Density of air at T = 10°C and p = 0.9 bar is given by:ρ = pM / RTWhere:M = Molecular weight of air, 0.0289644 kg/molR = Universal gas constant, 8.31432 J/(mol.K)T = Temperature, 283.15 KSubstituting the values we have:pM / RT = 0.9 × 0.0289644 / (8.31432 × 283.15)ρ = 1.144 kg/m³.
The velocity of the wind is not given, so we will assume it to be 10 m/s, which is equivalent to 22.37 mph.
Converting the diameter of the turbine from feet to meters:D = (75 + 1.25) × 0.3048D = 23.47 m,
Swept area of the blades is given by:A = πr²where:r = radius of the blade = D / 2A = π(D / 2)²A = π(23.47 / 2)²A = 430.7 m².
Putting the values in the formula:P = (1/2)ρA v³ nP = (1/2) × 1.144 × 430.7 × (10)³ × 0.25P = 153994.8 watts.

This final part of the project is the last for the birthday paradox program and combines everything from the modules to simulate the scenario of people in a group sharing a birthday. For this task you'll be required to create a Graphical User Interface (GUI) that calls the user-defined functions you created in module 2 to help perform the simulation. Graphical User Interfaces are what we're most familiar with when using computer programs; they consist of pop-up windows with buttons, text boxes, drop-down menus, radio buttons and other graphical elements that can be interacted with by a user to input information into the program. User-defined functions allow for effective code reuse and is good programming practice when creating programs that require the same or similar code to be executed many times. For this part of the project, you're required to simulate the birthday scenario: Call your function from module 2a to assign random birthdays to people in an increasingly large group of people (starting with a group size of 2 people and ending with a group size of 365). This function can be modified so it just generates whole numbers from 1 to 365 to represent each day (rather than the day/month format from module 2a), this will make the program less computationally complex but will still give you the same result. Use the function from module 2b to check these dates to see if there are any repeated birthdays in the groups. Keep a record of any matches discovered. Using the knowledge gained from module 1, you'll then plot a graph of the probabilities of a shared birthday from your simulation with a graph of the theoretical model overlayed (x-axis = group size, y-axis = probability). The graph must be displayed on your GUI (so you'll use app.UIAxes to display your results). To obtain a close statistical model to the theory, you'll need to repeat your simulation many times and take the average over the number of realisations (at least 10 times, but less than 500 times to ensure the simulation doesn't take too long). Your GUI must be able to obtain user input including: How many realisations does the user want in order to obtain an estimate of the probability of a shared birthday (allow user to select numbers between 10 and 500). This will allow the simulation to either be fast but less accurate (10 times) or slow and more accurate (500 times). - The maximum group size the user wants simulated. This will truncate the graph to the maximum group size. The range of this must be a minimum of 2 people and a maximum of 365 people in a group. You'll need to think not only about the way your program calculates the output required to solve the problem (its functionality) but also how your GUI will look (its aesthetics) and how simple it is for a user to input and receive output from your program (its usability). Your graphical user interface (GUI) must be created in App Designer (DO NOT use the menu () or dialog () functions or GUIDE!!!).

The LEFT side of the plate is insulated while the other side is exposed to an environment at 25° C with a heat transfer coefficient of 44 W/m².K. Calculate the temperature of plate 2 cm from the RIGHT side of the plate.
Given parameters:
Thickness, L = 6 cm = 0.06 m
Thermal conductivity, k = 115 W/m.K
Heat generated, q = 2 x 10^5 W/m^2Heat transfer coefficient, h = 44 W/m^2.
KTemperature of environment,
[tex]T_inf[/tex] = 25°C
The steady-state heat conduction through the plate is given by the equation:
q = -kA [dT/dx]
Where, A = Area of the plate, dT/dx = Temperature gradient[tex]T_inf[/tex]
As the heat is generated uniformly, heat generation term is positive and negative sign is introduced due to the temperature gradient, dT/dx being in the opposite direction of heat flow.
On integrating the above equation, we get:
dT/dx = -q/ kA (x - L) + C1
Where, C1 is a constant of integration and is evaluated using the boundary condition that at x = 0, T = T_s;
where T_s is the temperature at the insulated surface of the plate.
Therefore, we get:
C1 = qL/ 2kA + T_s
Also, the other boundary condition is that at x = 0.02 m (2 cm from the right surface), the temperature of the plate is T = T_r.
Therefore, substituting these values and solving for T_r, we get:
[tex]T_r = T_inf + qL/ (2kA) (1 - 2x/L)[/tex]
= 25 + 2 x 10^5 x 0.06 / (2 x 115 x 0.06 x 0.06) (1 - 2 x 0.02/0.06)

The velocity that will initiate cavitation is 48 mm/s.
The given data is as follows:Given: The minimum pressure on an object moving horizontally in water at a temperature of 10 degrees centigrade at (x+5) mm/s at a depth of 1 m is 80 kPa (absolute)Here, x = 43.
Therefore, the given velocity will be (x + 5) = 48 mm/s.
Assuming atmospheric pressure as 100 kPa (absolute)For cavitation, we need to calculate the absolute pressure at which cavitation will occur.
So, we have:P + (1/2)ρv^2 = P_vwhere,P = absolute pressure,ρ = density of water = 1000 kg/m^3v = velocity of waterP_v = Vapour pressure at a particular temperature.
For water at 10 degrees centigrade, the vapour pressure is 2.34 kPa (absolute)Now, substituting the values of P, ρ, and P_v, we get:80 + (1/2) × 1000 × (0.048)^2 = 2.34 + P_cwhere P_c is the absolute pressure at cavitation.
Therefore, P_c = 101.9 kPa (approx).
So, the velocity that will initiate cavitation is 48 mm/s.\
Given velocity = (x+5) = 48 mm/sAssuming atmospheric pressure as 100 kPa (absolute)P + (1/2)ρv^2 = P_vFor water at 10 degrees centigrade, the vapour pressure is 2.34 kPa (absolute)P_c = 101.9 kPa (approx).
Therefore, the velocity that will initiate cavitation is 48 mm/s.
When an object is moving horizontally in water at a temperature of 10 degrees centigrade at 48 mm/s at a depth of 1 m, the absolute pressure at which cavitation will occur is 101.9 kPa (approx). Therefore, the velocity that will initiate cavitation is 48 mm/s.

Write a Java method called iseven. The method takes an integer argument and returns true if it is even, and returns false otherwise. b. Include your method into a Java program that reads a sequence of integers. For each integer, the program should invoke the method isEven and print a message indicating if this integer is even or odd. The user could stop the program via entering the value -1.
Here's the solution in Java:
```java
import java.util.Scanner;
public class EvenOddChecker {
public static boolean isEven(int number) {
return number % 2 == 0;
}
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int number;
do {
System.out.print("Enter an integer (-1 to exit): ");
number = scanner.nextInt();
if (number != -1) {
boolean isEven = isEven(number);
String message = isEven ? "even" : "odd";
System.out.println(number + " is " + message);
}
} while (number != -1);
System.out.println("Exiting the program.");
scanner.close();
}
}
```
- The `isEven` method takes an integer argument and checks if it is even by using the modulus operator `%`. If the number modulo 2 equals 0, it returns `true`; otherwise, it returns `false`.
- In the `main` method, we use a `Scanner` to read the sequence of integers from the user.
- We use a `do-while` loop to continuously prompt the user for an integer until the user enters -1 to exit.
- For each integer entered, we invoke the `isEven` method to check if it is even or odd.
- The program prints a message indicating whether the integer is even or odd.
- Finally, when the user enters -1, the program exits.
The `isEven` method in the Java program takes an integer as input and returns `true` if it is even and `false` otherwise. The program reads a sequence of integers from the user and uses the `isEven` method to determine if each integer is even or odd. The program continues until the user enters -1 to exit.

This load balancing problem is NP-hard. Design an approximation algorithm. Consider the following greedy algorithm.
Set a counter i = 1. Assign the task ti to a machine with a minimum assigned processing load. Increment i, and continue until all tasks have been scheduled. Let T* denote the time by which all tasks are completed in an optimal schedule, and let T denote the time by which all the tasks are completed in the greedy schedule above. Prove the following:
1.). T* ≥ maxi pi
2). T* ≥ ( summation pi from i=1 to n )/m
3.) T ≤ 2T* ie the greedy algorithm gives a 2-approximation using (1) and (2)
The total running time of the algorithm is O(nlogn).Hence, the greedy algorithm for the minimum waiting time has a time complexity of O(nlogn).
Given the task duration of n tasks is to be minimized, the greedy algorithm for the minimum waiting time can be proposed as follows:
Sort the given tasks in decreasing order of their execution times, i.e.,
sort ti, i = 1, 2, ..., n in non-increasing order. After sorting, assign the first task (with the largest execution time) to start at time t0, and each subsequent task to start at the time when all previous tasks have been completed.
The above process ensures that tasks that take longer to execute are executed first. This ensures that the waiting time for each task is minimized. Now, we prove the optimality of the algorithm.
For the proof of optimality, let's consider a counter-example where the optimal solution is not the greedy one.
Suppose we have three tasks, (t1=3, t2=2, t3=2). Now, the greedy algorithm will schedule the tasks in the order (t1, t2, t3), with waiting times of (0, 3, 5).
However, the optimal solution is to schedule the tasks in the order (t1, t3, t2), with waiting times of (0, 3, 4).This counter-example proves that the greedy algorithm does not always give the optimal solution.

A 400-V, three-phase, Y_connected, the synchronous motor has a synchronous reactance of 20 ohm/phase. Its armature resistance is negligible. When the motor runs at a speed of 180 rad/s, it consumes 8 kW and the excitation voltage is 500 V. The power factor can be determined by using the following steps: Find the current per phase by using the power formula.
Apply Ohm's law to find the impedance per phase. Calculate the phase angle using the reactance and impedance values. Use cosine to find the power factor.
Given that: Voltage, V = 400VExcitation voltage, E = 500VCurrent, I =?Power, P = 8kW
Synchronous reactance, Xs = 20ΩSpeed, N = 180 rad/sThe formula to find the power is given by, P = 3 V I cos φor P = VI cos φor cos φ = P / VIWhere φ is the phase angle. We can find the current per phase by using the power formula, P = 3 V I cos φ, where I = P / (3 V cos φ)= 8000 / (3 × 400 cos φ)= 6.667 / cos φ per phase impedance per phase can be calculated by applying Ohm's law,Z = V / I = 400 / (6.667 / cos φ) = 60 cos φ ΩThe reactance of the synchronous motor is given by Xs = 20 Ω/phaseTherefore, the inductive component of the impedance per phase is 20 Ω, and the resistance is negligible. The phase angle can be calculated using the reactance and impedance values. Therefore, sin φ = Xs / Z= 20 / 60 cos φ= 1 / 3 cos φ= 0.333 cos φφ = 19.47°Using cosine, we can calculate the power factor as follows: cos φ = cos (19.47) = 0.944Therefore, the power factor is 0.94D
Therefore, the power factor of the given synchronous motor is 0.94D.

You have some data where customer's last & first names are listed in one field, "Jones, Mike". You are tasked to create a python function named 'parse_name' that will accept a string input and return a list with the names seperated and ordered by first name and then last name. Create the function in the cell below
The code for the Python function named `parse_name` to accept a string input and return a list with the names separated and ordered by first name and then last name is provided below The Python function `parse_name` is created to accept a string input and return a list with the names separated and ordered by first name and then last name.
The function takes in one parameter which is the string input. The first line of the function splits the string using the `split` method on the comma `,` that separates the last name and first name. The `split` method returns a list of two items, the last name and first name.The next line of the function splits the second item in the list using the `split` method again on the whitespace ` ` that separates the first name and the last name. The `split` method returns a list of two items, the first name and last name.The final line of the function returns a new list that contains the first name and last name in the correct order. This list is obtained by indexing into the list of split strings that we obtained in the first two lines. The index `[1]` is used to get the first name, while the index `[0]` is used to get the last name. These are then concatenated into a new list using the `+` operator.
