# Daily Challenge #58

Today’s daily challenge is to ask for a 3-digit number and return the greatest number that can be formed using the same digits.

``````greatest(128) => 821
greatest(503) => 530
greatest(170) => 710
greatest(888) => 888
greatest(910) => 910
``````

Have fun!

What if the given number is already the greatest number? should the program return the same number again or say: “the given number is already the greatest, there is no greater number”

Return the greatest number, will add a sample to my original post.

I thought why to reinvent the wheel when we have a bubble sorting procedure. So i took the whole number and i split all digits and place them in a list. Then the bubble sorting procedure did the job. It works with more than 3 digits.

Very impressive, good job! Would be nice to see the number returned instead of the sorted list, but amazing!
