A left rotation operation on an array of size n 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=[1,2,3,4,5] After 2 rotations, arr'=[3,4,5,1,2]. Function Description: Complete the rotateLeft function in the editor below. rotateLeft has the following parameters: 1. int d: the amount to rotate by 2. int arr[n]: the array to rotate Returns 1. 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: 1. 1<=n<=10^5 2. 1<=d<=n 3. 1<=a[i]<=10^6
A left rotation operation on an array of size n 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=[1,2,3,4,5]
After 2 rotations, arr'=[3,4,5,1,2].
Function Description:
Complete the rotateLeft function in the editor below.
rotateLeft has the following parameters:
1. int d: the amount to rotate by
2. int arr[n]: the array to rotate
Returns
1. 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:
1. 1<=n<=10^5
2. 1<=d<=n
3. 1<=a[i]<=10^6
