Your 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
