Rotate number to form the maximum number using JavaScript
Problem
We are required to write a JavaScript function that takes in a number n. Our function is required to return the maximum value by rearranging its digits.
Example
Following is the code −
const num = 124; const rotateToMax = n => { n = n .toString() .split('') .map(el => +el); n.sort((a, b) => return b - a; }); return n .join(''); }; console.log(rotateToMax(num));
Output
421
