Arrays left rotation

left rotation operation on an array shifts each of the array's elements  unit to the left. For example, if  left rotations are performed on array , then the array would become .
Given an array  of  integers and a number, , perform  left rotations on the array. Return the updated array to be printed as a single line of space-separated integers.
Function Description
Complete the function rotLeft in the editor below. It should return the resulting array of integers.
rotLeft has the following parameter(s):
  • An array of integers .
  • An integer , the number of rotations.
Input Format

The first line contains two space-separated integers  and , the size of  and the number of left rotations you must perform.
The second line contains  space-separated integers .
Constraints
  • ≤ n ≤ 10
  • 1≤d≤n
  • 1≤a[i]≤10
Output Format


Print a single line of  space-separated integers denoting the final state of the array after performing  left rotations.
Sample Input
5 4
1 2 3 4 5
Sample Output:
5 1 2 3 4

Explanation:
When we perform  left rotations, the array undergoes the following sequence of changes:
[1,2,3,4,5] → [2,3,4,5,1]  [3,4,5,1,2]  [4,5,1,2,3]  [5,1,2,3,4]
Program:
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;
public class Solution {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        int n = sc.nextInt();
        int d = sc.nextInt();
        int array[] = new int[n];        
        for (int i=0; i<n; i++)
            array[i] = sc.nextInt();  
        for (int i=0; i<n; i++)
            System.out.print(array[(i+d)%n] + " ");
    }
}
