Batch totals are not incorporated while designing real-time applicationsD. 4GLs are used for application proto typingE. None of the above
Answer:
A structured chart is a sequential representation of program design
Explanation:
It is true that a real-time system which is a term to describe an operating system working in relation to real-time is actually a form of the online system. Hence, option B is not correct.
It is also true that Batch totals are not incorporated while designing real-time applications because Batch Data processing is carried out in a separate manner and at a time when the computer is free. Thus Option C is not Correct
It is also true that 4GL which stands for Forth generation programming language is used for application prototyping. Again Option D is not Correct.
However, a structured chart is not a sequential representation of program design, but rather a break down to the infinitesimal module in the program design. Hence, option A is the correct answer.

. (a) Prove or disprove carefully and in detail: (i) Θ is transitive and (ii) ω is transitive. (b) Assume n is a positive integer. Algorithm A(n: int) int z = 0; int temp = 0; for (int i = 0; i < n ; i++) { for (int j = 0 ; j < i ; j++) { int temp = i + j ; int z = z + temp; } } System.out.println(z) ; What is the input size for Algorithm A? Analyze carefully and explicitly the time complexity of A in terms of the input size. Show all steps. Is A a polynomial time algorithm? Justify your answer.
Answer:
The Following are the solution to this question:
Explanation:
In Option a:
In the point (i) [tex]\Omega[/tex] is transitive, which means it converts one action to others object because if [tex]\Omega(f(n))=g(n)[/tex] indicates [tex]c.g(n)<=f(n)[/tex]. It's true by definition, that becomes valid. But if [tex]\Omega(g(n))=h(n)[/tex], which implies [tex]c.h(n)<=g(n)[/tex]. it's a very essential component. If [tex]c.h(n) < = g(n) = f(n) \[/tex]. They [tex]\Omega(f(n))[/tex] will also be [tex]h(n)[/tex].
In point (ii), The value of [tex]\Theta[/tex] is convergent since the [tex]\Theta(g(n))=f(n)[/tex]. It means they should be dual a and b constant variable, therefore [tex]a.g(n)<=f(n)<=b.g(n)[/tex] could only be valid for the constant variable, that is [tex]\frac{1}{a}\ \ and\ \ \frac{1}{b}[/tex].
In Option b:
In this algorithm, the input size value is equal to 1 object, and the value of A is a polynomial-time complexity, which is similar to its outcome that is [tex]O(n^{2})[/tex]. It is the outside there will be a loop(i) for n iterations, that is also encoded inside it, the for loop(j), which would be a loop[tex](n^{2})[/tex]. All internal loops operate on a total number of [tex]N^{2}[/tex] generations and therefore the final time complexity is [tex]O(n^{2})[/tex].
Which are elements involved in modeling a solution? Choose all that apply. A) often includes a visual graphic B) shows the flow of information from task to task C) assigns demands D) breaks the solution into tasks E) includes pseudocode
Often includes a visual graphic, shows the flow of information from task to task, breaks the solution into tasks and includes pseudocode are elements involved in modeling a solution. Hence, options A, B, D and E are correct.
What is pseudocode?Pseudocode is a made-up, informal language that aids in the creation of algorithms by programmers. A "text-based" detail design tool is pseudocode. The Pseudocode rules are not too complicated. Statements that demonstrate "dependence" must all be indented. Some of these are while, do, for, if, and switch.
Pseudo code: It's just a plain text document with annotations and informative text that implements an algorithm. It has no grammar like any other programming language, making it impossible for a computer to compile or interpret.
A simplified version of an algorithm that expresses coding logic in English is known as pseudocode. It enables programmers to plan the architecture of any algorithm using straightforward commands. Pseudocode describes numerous coding actions and their proper order mostly in plain English.
Thus, options A, B, D and E are correct.

Explanation:
where are the choices
Consider sorting n numbers stored in array A by first finding the smallest element of A and exchanging it with the element in A[1]. Then find the second smallest element of A, and exchange it with A[2]. Continue in this manner for the first n − 1 elements of A. Write pseudocode for this algorithm, which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the first n − 1 elements, rather than for all n elements? Give the best–case and worst–case running times of selection sort in Θ–notation.
Answer:
1. create the first array A
2. create the second array A1, the same length as array A.
3. create a loop to iterate over both arrays for a number of times specific to the length of the arrays, with a condition to get and pop only the minimum value of which arrays for every loop.
4. save both items to "a" for minimum value A and "b" for minimum value A1.
5. call a function to push the "a" variable value to A1 and "b" variable value to the array A.
Explanation:
This code would interchange the values of both arrays, the best-case scenario for the code is O( n ) where n is the number of items in both arrays and worst is the best-case multiplied by the number of time to compare all the items with the minimum value.

I don't think a pocket watch is considered a computer based off of my logic. Other people may think differently tho.
Explanation:
You want to decide whether you should drive your car to work or take the train. You know the one-way distance from your home to your place of work, and the fuel efficiency of your car (in miles per gallon). You also know the one-way price of a train ticket. You assume the cost of gas at $4 per gallon, and car maintenance at 5 cents per mile. Write an algorithm to decide which commute is cheaper.
Explanation:
Remember, an algorithm in simple words means a set of instructions or steps to be followed in other to solve a problem.
Note, to decide which commute is cheaper, it means the output of the algorithm should be the cheaper way to commute.

Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example output for userNum = 40: 20 10 5 2 1 Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 40, then with userNum = 2, then with userNum = 0, then with userNum = -1. See "How to Use zyBooks". Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message.
Answer:
public class Main
{
public static void main(String[] args) {
int userNum = 40;
while(userNum > 1){
userNum /= 2;
System.out.print(userNum + " ");
}
}
}
Explanation:
*The code is in Java.
Initialize the userNum
Create a while loop that iterates while userNum is greater than 1. Inside the loop, divide the userNum by 2 and set it as userNum (same as typing userNum = userNum / 2;). Print the userNum
Basically, this loop will iterate until userNum becomes 1. It will keep dividing the userNum by 2 and print this value.
For the values that are smaller than 1 or even for 1, the program outputs nothing (Since the value is not greater than 1, the loop will not be executed).

Assume that you are able to do an exhaustive search for the key to an encrypted message at the rate of 100 Million trials per second. How long in (days or years) would it take for you to find the key to a code that used a 112-‐‑bit key on average? What encryption algorithm might have been used by the encryption system? (Give the name of an encryption algorithm that uses 112-‐‑bit-‐‑key.)
Answer:
Following are the solution to this question:
Explanation:
In point 1:
Trials frequency [tex]= \frac{100 \ million }{second}[/tex]
calculating the main length of cryptography = 112 bit
[tex]\to 100\ Million = 1 \times 10^8[/tex]
calculating the second year value:
[tex]\to 365 \times 24 \times 60 \times 60 =3153600\\\\[/tex]
[tex]=3.15 \times 10^7 \ seconds[/tex]
Currently, in average , at least half the possible sleeves is being used to verify the encryption process: [tex]2^{111} \ keys[/tex]
[tex]\to \frac{2^{111} \time3s 10^6}{3.15 \times 10^7}\approx 8.22 \times 10^{20} \ years[/tex]
the total time value will be [tex]8.22 \times 10^{20} \ years[/tex]
In point 2:
In cryptography, the common name is Triple DES (3DES), which would be the symmetric-key encrypted communication algorithm (TDEAor Triple DEA), which adds 3 times per block size only with the cryptographic method Data Encryption Standard ( DES).
Algorithm:-
The key package involves four DES keys, K1, K2, and K3, each 56-bit (except parity bits), Triple DES includes. Its encoding algorithm is::
[tex]ciphertext = EK3(DK2(EK1(plaintext)))[/tex]
I.e. K1, DES encrypt, K2 decrypt, then K3 encrypt DES.
The reverse is the decryption:
[tex]plaintext = DK1(EK2(DK3(ciphertext)))[/tex]
I.e. decrypt by K3, crypt by K2, decrypt by K1.
Every three-bit authentication encrypts a 64-bit block.
Its middle procedure in each situation it's the reverse of the first operation. It improves the strength of the key second option algorithm which offers DES native support with key option 3.
