This is brilliant because it encourages thinking a little differently to come up with the wrong answer (which helps you learn to identify wrong code). Nice work OP

1. Generate all permutations of the input. 2. Return the permutation that is in order. 3. Profit!

Well, a lot of them aren't wrong answers, just really inefficient or overly-complicated implementations.

The ultimate answer is to ask your young siblings to sort them for you. The price is a little time and some candy. Or since so many people are unemployed, ask them to crowdsource and work for something in return!

Or just ask wolframalpha.
