Challenge: Right Rotate an Array by 1
Given an array, can you rotate its elements by one index from right to left? Implement your solution in C++ and see if your code runs successfully.
We'll cover the following
Problem Statement
Implement a function rightRotate(int arr[], int size) which takes an array arr and rotate it right by 1. This means that the right-most elements will appear at the left-most position in the array.
Input
An array of integers and its size.
Output:
The given array rotated by 1.
Sample Input
arr = [1,2,3,4,5]
Sample Output
arr = [5,1,2,3,4]
