Implement pow(x, n) % M.
In other words, given x, n and M, find (xn
) % M.
 

Example 1:

Input: 3 2 4
Output: 1

Example 2:

Input: 10 9 6
Output: 4

 

Your Task:
You don't need to read or print anything. Your task is to complete the function PowMod() which takes the x, n and M as input parameters and returns xn % M.

 

Expected Time Complexity: O(log(n))
Expected Space Complexity: O(1)

 

Constraints:
1 <= x, n, M <= 100000

** For More Input/Output Examples Use 'Expected Output' option **
