Given an array, rotate the array by one position in clock-wise direction.
Example 1:
Input:
N = 5
A[] = {1, 2, 3, 4, 5}
Output:
5 1 2 3 4
Example 2:
Input:
N = 8
A[] = {9, 8, 7, 6, 4, 2, 1, 3}
Output:
3 9 8 7 6 4 2 1
Your Task:
You don't need to read input or print anything. Your task is to complete the function rotate() which takes the array A[] and its size N as inputs and modify the array in place.
Expected Time Complexity: O(N)
Expected Auxiliary Space: O(1)
Constraints:
1<=N<=105
0<=a[i]<=105
