Approach by using the functools.reduce method
We have used the reduce function from the functools module to iteratively multiply all elements in the input array and calculate the remainder after each multiplication operation when divided by the given number n.
Below is implementation for the above approach:
Python3
from functools import reducedef remainderAfterMultiplication(arr, n): result = reduce(lambda x, y: (x * y) % n, arr) return result# Driver Codearr1 = [100, 10, 5, 25, 35, 14]n1 = 11result1 = remainderAfterMultiplication(arr1, n1)print(result1)arr2 = [100, 10]n2 = 5result2 = remainderAfterMultiplication(arr2, n2)print(result2) |
9 0
Time Complexity: O(len), where len is the size of the given array
Auxiliary Space: O(1)

Python Program for Find remainder of array multiplication divided by n
Write a Python program for a given multiple numbers and a number n, the task is to print the remainder after multiplying all the numbers divided by n.
Examples:
Input: arr[] = {100, 10, 5, 25, 35, 14},
n = 11
Output: 9
Explanation: 100 x 10 x 5 x 25 x 35 x 14 = 61250000 % 11 = 9
Input : arr[] = {100, 10},
n = 5
Output : 0
Explanation: 100 x 10 = 1000 % 5 = 0
