Can anyone tell me how this would compare to just using the method in terms of efficiency?

Wouldn't this require more space to make a copy of the method or is there more to it?

Thank you! And how do I do that? I'm normally pretty good with these kinds of things, but for whatever reason this site is very unintuitive for me.

Your function doesn't return anything. And next time you should leave kata-related questions in the discourse of the kata you're training on.

Sorry I'm new, how do I do that?

this?

My output matches directly with what is expected yet it seems to think they don't match.
