/*
Problem: Rotated an array by given k elements in clockwise manner.

Sample I/O:

Enter size of array:4
Enter elements:1 2 3 4
Rotate array by how many elements:15
Rotated array is 
2 3 4 1 

Enter size of array:5
Enter elements:1 2 3 4 5
Rotate array by how many elements:2
Rotated array is 
4 5 1 2 3

Time Complexity: O(n)
Space Complexity : O(n)
