I've similiar solution and I've spent a while trying figure out how to avoid using .filter to get rid of empty string created during replacement. Is there any better way to do that?

i love this holy shiz. looking at these solutions is really making me think about solutions differently.

i was way off and only got through psuedo-code but this solution is what i was vaguely grasping at

clever and simple

Thanks!

so good!

definitely the cleanest version of these solutions, although I feel people will vote for something more cheeky..

Not only this is hard to read, but the performance is not very good.

It isn't one loop. It filters (and sorts) twice. EDIT: nevermind, I see that you're asking how one might do it in one loop.

Oki. I thought my solution has big problems with performance. But how can u do it using one loop?

No idea, just copied and pasted it and it still works for me. Why wouldn't it work?

This solution does not pass the test. Has something changed or been updated?

Thanks for pointing that out, I have a lot to learn.

No need to overcomplicate the task. U r given a straightforward task which presumes an array of only positive integers
