Sum of two numbers modulo M

Given three numbers A, B, and M. The task is to print the sum of A and B under modulo M. 

Examples: 

Input: a = 10, b = 20, m = 3 
Output: 0
Explanation: (10 + 20) % 3 = 30 % 3 = 0

Input: a = 100, b = 13, m = 107 
Output: 6

Approach: To solve the problem follow the below idea:

Add the two given numbers A and B and print their sum under modulo M.

Below is the implementation of the above approach:
