I ran the tests a few times, and it seems using in is more time effective, but the difference is negligible.

Could someone take a look at this? The kata author is no longer active.

I'm aware, just forgot to change the name of the kumite.

He probably tried to figure something out for himself, not to actually improve the code.
In case you do this in the future, your code also gets saved when you just press save. Publish is only if you want to make your code (normally with improvements) public.

What's the point of this? You included my code but didn't improve it. You just added some junk that makes it even less readable.
