Left Rotation

[ndrohith09]

A left rotation operation on an array of size shifts each of the array's elements 1 unit to the left. Given an integer, d , rotate the array that many steps left and return the result.

Example

d = 2 
arr = [1,2,3,5] 
After 2 rotations, arr' = [3,4,5,1,2] 

Function Description

Complete the rotateLeft function in the editor below.
rotateLeft has the following parameters:

• int d: the amount to rotate by
• int arr[n]: the array to rotate

Returns

• int[n]: the rotated array

Input Format

The first line contains two space-separated integers that denote n , the number of integers, and , d the number of left rotations to perform.
The second line contains n space-separated integers that describe arr[].

Constraints
