Easy Accuracy: 14.15% Submissions: 106 Points: 2

Given three numbers a, b and c such that a, b and c can be at most 1016. The task is to compute (a*b)%c

Example 1:

Input: a = 4, b = 3, c = 5
Output: 2
Explanation: (4 * 3) = 12 and
12 % 5 = 2

​Example 2:

Input: a = 1000000000007,
b = 10000000000005, c = 1000000000000003
Output: 74970000000035
Explanation: You can calculate it by youself.

Your Task:  
You don't need to read input or print anything. Your task is to complete the function mulMod() which takes a, b, c as inputs and returns the answer.

Expected Time Complexity: O(1)
Expected Auxiliary Space: O(1)

Constraints:
1 ≤ a, b, c ≤ 1016
