how do you call the squares method to compute the first five squares and store the result in an array numbers

IRINA_888 [86]

Answer:

The method can be called using:

int[] returnarray = Squares();

Where returnarray represents the name of the array

Explanation:

To answer this, I will make an assumption that the Square method is an int array method (i.e. it returns array).

So, to call the method from main, an array has to be declared to get the values:

int[] returnarray = Squares();

Then an iteration is created to iterate through the array in order to print the array elements.

for (int i = 0; i < returnarray.length; i++)

System.out.print(returnarray[i]+ " ");

-------------------------------------------------------------------------------------------

The answer ends here

-------------------------------------------------------------------------------------------

As an addition, the complete program that includes the method and the main is:

public class Main{

public static int [] Squares(){

int [] arr = new int[5];

for(int i = 1;i<6;i++){

arr[i-1] = i*i;

}

return arr;

}

public static void main(String[] args) {

int[] returnarray = Squares();

for (int i = 0; i < returnarray.length; i++)

System.out.print(returnarray[i]+ " ");

}

}

Explain how any simple substitution cipher that involves a permutation of the alphabet can be thought of as a special case of th

Kaylis [27]

A simple substitution cipher takes each vector ( $e_i$ ) and assigns it to the vectors [ $e_{\pi (i)}$ ] in a one-to-one function so as to make them equivalent.

<h3>What is the Hill cipher?</h3>

In 1929, the Hill cipher was invented by Lester S. Hill and it can be described as a poly-graphic substitution cipher that is typically based on linear algebra and it avails a cryptographer an ability to simultaneously operate on more than three (3) symbols.

In Cryptography, the simple substitution cipher is usually viewed as a function which takes each plaintext letter (alphabet) and assigns it to a ciphertext letter. Thus, it takes each vector ( $e_i$ ) and assigns it to the vectors [ $e_{\pi (i)}$ ] in a one-to-one function so as to make them equivalent.
