How to use functional approach with reduce() In Javascript
In this approach, a functional programming style is employed along with the reduce() function to find the remainder of the array multiplication when divided by a given number ‘n’.
Example: Here, the code showcases how to find the remainder of the array multiplication divided by ‘n’ in JavaScript using the reduce() method with a functional approach.
Javascript
function findRemainder3(arr, n) { return arr.reduce((acc, val) => { (acc * val) % n, 1 }); } let arr3 = [1, 2, 3, 4]; let n3 = 17; console.log(findRemainder3(arr3, n3)); |
undefined
Time Complexity: O(n)
Space Complexity: O(1)
JavaScript Program to Find Remainder of Array Multiplication Divided by n
In JavaScript, the remainder of the array multiplication when divided by the number n can be found by iteration, functional programming or array reduction. , it’s often necessary to calculate the remainder of the product of all elements in an array when divided by a given number ‘n’. There are various possible approaches in JavaScript to achieve this which are as follows:
