noobCode 01: SUPERSIZE ME.... or rather, this integer!

zltzlt

Write a function that rearranges an integer into its largest possible value.

1. superSize(123456); // 654321
   
2. superSize(105); // 510
   
3. superSize(12); // 21

If the argument passed through is single digit or is already the maximum possible integer, your function should simply return it.

1. function superSize(num){
   
2.     var a = num.toString().split("");
   
3.     a.sort(function(x, y) {if (parseInt(x) > parseInt(y)) {return 1;} return -1;});
   
4.     a.reverse()
   
5.     return parseInt(a.join(""))
   
6. }
