Descending Order

our task is to make a function that can take any non-negative integer as a argument and return it with its digits in descending order. Essentially, rearrange the digits to create the highest possible number.

Examples:

Input: 21445 Output: 54421

Input: 145263 Output: 654321

Input: 1254859723 Output: 9875543221

reply

function descendingOrder(n){
  return Number(String(n).split("").sort((a,b)=>b-a).join(""));
}
