Took me some time to figure this out. I stepped away for a bit, came back, and figured it out pretty quickly. I could see this being incredibly hard or incredibly easy depending on your mindset.

I do agree the directions are a bit lacking and you kind have to figure out a lot of the requirements yourself. (Replacing _ with spaces for example).

However, as someone who is trying to improve with regex, this actually helped me learn a lot. So I'm kind of glad the instructions were a little parse.

Lol. I love this for obvious reasons, despite it being a terrible and broken solution.

Took me awhile to understand exactly what it was asking for. I assumed that it meant the order should be based off of when the numbers appear in the string.

So 2000 11 11 02 would return as 2000 11 11 02

But it's actually asking you to sort any equal numbers as if they were a string. So you need to compare them alphabetically to figure out the correct order.

Clean solution, but I would swap the 5 out for (fighters[position[0]].length - 1) to support if new fighters are ever added to the roster.
