Write a program that prompts the user to enter a string and displays the maximum consecutive increasingly ordered substring. Ana

Marianna [84]

Answer:

a.

// Program is written in Java Programming Language

// Comments are used for explanatory purpose

// Comments marked x represents simple statements

// Comments marked y represents single loop

// Program starts here

import java.util.*;

public class MaxOrder {

public static void main(String args [] ) {

Scanner accept = new Scanner(System.in);

LinkedList<Character> maxtext = new LinkedList<>();

LinkedList<Character> textlist = new LinkedList<>();

System.out.print("Enter a text: ");

String text = accept.nextLine();

// Find the maximum consecutive increasingly ordered substring

for (int i = 0; i < text.length(); i++) { // y1

if (textlist.size() > 1 && text.charAt(i) <= textlist.getLast() && textlist.contains(text.charAt(i))) {

textlist.clear(); // x

}

textlist.add(text.charAt(i)); // x

if (textlist.size() > maxtext.size()) { // x

maxtext.clear();

maxtext.addAll(list);

}

// Display the maximum consecutive

// increasingly ordered substring

for (Character ch: maxtext) { // y2

System.out.print(ch); // x

}

System.out.println();

}

b. Analysing the time complexity

In single loop marked y1, there are 3 simple statements ----- 1

In single loop marked y2, there is 1 simple statement --_--- 2

In (1) above,

1 single loop * 3 simple statements = 3;

*

In (2) above,

1 single loop * 1 simple statement = 1;

So, we have

T(n) = O(n) Linear time

Depends if your encoder has ENABLE input..
if so see my attached image.

Assume that you have an array of integers named a. Which of these code segments print the same results?

Harrizon [31]

Answer: II and III only

The first code will print starting with the second variable in the array. So it will start with array[1] instead of starting with array[0]

The second code will start from array[0] as the variable i is 0. It will print the first value in the array before proceeding to increment the value of i.

The third code will also start from array{0] as the program will check for the first value of a before proceeding to the next one.

An example would be if we were to define the array as:

int[] a = {1,2,3,4,5};

1st Code Output:

2

3

4

5

2nd Code Output:

1

2

3

4

5

3rd code Output:

1

2

3

4

5

Always remember that arrays will always begin from 0.

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 se

Len [333]

Answer:

Following are the solution to this question:

Explanation:

In point 1:

Trials frequency $= \frac{100 \ million }{second}$

calculating the main length of cryptography = 112 bit

$\to 100\ Million = 1 \times 10^8$

calculating the second year value:

$\to 365 \times 24 \times 60 \times 60 =3153600\\\\$

$=3.15 \times 10^7 \ seconds$

Currently, in average , at least half the possible sleeves is being used to verify the encryption process: $2^{111} \ keys$

$\to \frac{2^{111} \time3s 10^6}{3.15 \times 10^7}\approx 8.22 \times 10^{20} \ years$

the total time value will be $8.22 \times 10^{20} \ years$

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::

$ciphertext = EK3(DK2(EK1(plaintext)))$

I.e. K1, DES encrypt, K2 decrypt, then K3 encrypt DES.

The reverse is the decryption:

$plaintext = DK1(EK2(DK3(ciphertext)))$

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.
