Product sum difference of digits of a number in JavaScript
Problem
We are required to write a JavaScript function that takes in a number n. Our function should find the absolute difference between the sum and the product of all the digits of that number.
Example
Following is the code −
const num = 434312; const sumProductDifference = (num = 1) => { const sum = String(num) .split('') .reduce((acc, val) => acc + +val, 0); const product = String(num) .split('') .reduce((acc, val) => acc * +val, 1); const diff = product - sum; return Math.abs(diff); }; console.log(sumProductDifference(num));
Output
271
