Given an array Arr[ ] of N integers and a positive integer K. The task is to cyclically rotate the array clockwise by K.

Note : Keep the first of the array unaltered.

Example 1:

5 —Value of N
{10, 20, 30, 40, 50} —Element of Arr[ ]
2 —–Value of K

Output :

40 50 10 20 30

Example 2:

4 —Value of N
{10, 20, 30, 40} —Element of Arr[]
1 —–Value of K

Output :

40 10 20 30

code :

import java.util.*;


public class rotate {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        int n=sc.nextInt();

        int arr[]=new int[n];

        for(int i=0;i<arr.length;i++){
            arr[i]=sc.nextInt();
        }
        int k=sc.nextInt();

        // 12 20 30 40 50

        int arr2[]=new int[n];

        for(int i=0;i<k;i++){
            arr2[i]=arr[arr.length-1-i];
        }
        int j=0;
        for(int i=k;i<arr.length;i++){
            arr2[i]=arr[j++];
        }

        for(int i=0;i<arr2.length;i++){
           System.out.println(arr2[i]);
        }

    }
    
}
