Question

Fill an array (type int, size n).

Perform Left Circular Shift.

Answer 1

import java.util.*;
class clArraysSelection 
{
    public void main() 
    {
        Scanner sc = new Scanner(System.in);
        System.out.print(" Enter the array size : ");
        int n = sc.nextInt();
        int R[] = new int[n];
        int j = 0;
        for (j = 0; j < n; j++) 
        {
           System.out.print("Enter value for cell number " + (j) + “ : ");
           R[j] = sc.nextInt();
        }
        System.out.println("/t The array is: ");
        for(j = 0; j<n;j++)
        {
           System.out.print(" " + R[j]);
        }
        //left circular shift 
        int tmp = R[O];
        for(j= 1; j<n; j++)
        {
           R[j -1] = R[j];
        }
        R[n - 1] = tmp;
        System.out.println("\n\n The array after a left circular shift : ");
        for(j = 0; j<n; j++)
        {
           System.out.print("/t " + R[j]);
        }
    }
}

Output:

The array is : 

99 22 77 44 55 11

The array after a Left Circular Shift : 22 77 44 55 11 99
