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 .
The second line contains space-separated integers .
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]

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] + " ");
