dang what a nice answer bro

really hard for my brain to chew tho hahaha

it is possible, but the tests will not pass in all cases and not for all data. And since the data is generated dynamically, the complexity of sorting varies, as well as the correctness of the final sample.

What about mine? It's the replaceAll complementary

Long live to regex assertions

Maybe you want to add this to the description or does it 'spoil' too much?

Same goes for mine.

Thank you.

If I read test cases correctly, you are half way through as there's ~600 tests.

Well done sir!

nice.

@alexshavlovsky -- this is a good edge case suggestion; I wish I had thought of it while I was writing this kata. I'm not sure if I will be adding it, considering the number of kata completions at this time.

"efficiency" is generally related to time complexity, not space. ;) (but I have some extra layers there too, yes)

Thanks for the suggestions. I'm currently rather busy, so I'm not sure when I can come back and act on your advice, but I'll keep it in mind.

I know it's a little late, but I did adjust the tests just a bit. Goodluck.
