Find Remainder

Find Remainder


Determine the remainder from division of two positive integers.


Input: Two integers (int): dividend (the number to be divided) and divisor (the number by which division is to be performed).

Output: Integer (int).


assert find_remainder(10, 3) == 1
assert find_remainder(14, 4) == 2
assert find_remainder(27, 4) == 3
assert find_remainder(10, 5) == 0

How it’s used: remainder calculations are common in algorithms, especially in modular arithmetic which is frequently used in cryptography and computer graphics.


  • dividend, divisor > 0.
