Arrays left rotation

A 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

• 1 ≤ n ≤ 10⁵
• 1≤d≤n
• 1≤a[i]≤10⁶

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] + " "); 

    }

}
