Java Program to Split the array and add the first part to the end

Last Updated : 05 Dec, 2018

There is a given an array and split it from a specified position, and move the first part of array add to the end.

Examples:

Input : arr[] = {12, 10, 5, 6, 52, 36}
            k = 2
Output : arr[] = {5, 6, 52, 36, 12, 10}
Explanation : Split from index 2 and first 
part {12, 10} add to the end .

Input : arr[] = {3, 1, 2}
           k = 1
Output : arr[] = {1, 2, 3}
Explanation : Split from index 1 and first
part add to the end.

Java

// Java program to split array and move first
// part to end.

import java.util.*;
import java.lang.*;
class GFG {
    public static void splitArr(int arr[], int n, int k)
    {
        for (int i = 0; i < k; i++) {

            // Rotate array by 1.
            int x = arr[0];
            for (int j = 0; j < n - 1; ++j)
                arr[j] = arr[j + 1];
            arr[n - 1] = x;
        }
    }

    // Driver code
    public static void main(String[] args)
    {
        int arr[] = { 12, 10, 5, 6, 52, 36 };
        int n = arr.length;
        int position = 2;

        splitArr(arr, 6, position);

        for (int i = 0; i < n; ++i)
            System.out.print(arr[i] + " ");
    }
}
