Given a string str representing a large integer, the task is to find the result of N % 4.
Input: N = 81
Input: N = 46234624362346435768440
Approach: The remainder of division by 4 is dependent on only the last 2 digits of a number, so instead of dividing N we divide only the last two digits of N and find the remainder.
Below is the implementation of the above approach:
Time Complexity: O(1)
- Program to find remainder when large number is divided by r
- Program to find remainder when large number is divided by 11
- Remainder with 7 for large numbers
