In this article, we will learn about the solution to the problem statement given below −

Given multiple numbers and a number input n, we need to print the remainder after multiplying all the number divisible by n.

First, compute the remainder like arr[i] % n. Then multiply this remainder with the current result.

After multiplication, again take the same remainder to avoid overflow. This is in accordance with distributive properties of modular arithmetic.

( a * b) % c = ( ( a % c ) * ( b % c ) ) % c

def findremainder(arr, lens, n): mul = 1 # find the individual remainder for i in range(lens): mul = (mul * (arr[i] % n)) % n return mul % n # Driven code arr = [100,1,2,3,4,5,6,6,7] lens = len(arr) n = 11 print( findremainder(arr, lens, n))
