Chapter 7, Problem 15E

Explanation of Solution

Method “collapse()” to return the array by adding the pairs of value in the given array:

//Definition of class

public class Text

{

    //Definition of main method

    public static void main(String[] args)

    {

        //Create an array

        int[] list={1,6,2,1,4,1,2,1,8};

            //Call the array

            int t[] = collapse(list);

        //For loop to print the array

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

        {

            //Assign the evaluated value in "res"

            System.out.println(t[i]);

        }

    }

    //Definition of method collapse()

    public static int[] collapse(int[] list)

    {

        //Create the array list

int[] res = new int[list.length / 2 + list.length % 2];

//Traverse the for loop till it reaches the "res.length - list.length % 2"

for (int i = 0; i < res...
