Consider Codewars a panopoly of restaurants. Given the inclinations of your palate, you can freely choose where to eat your next meal.

Your assumption that this task requires math is also false. There are solutions that rely heavily on programming concepts such as iteration and recursion, with only minimal math. Anyway, I would never downvote a good quality code challenge, even if I don't like it. But you vote however you want. I just think it's better you stay from (what you consider to be) math heavy kata's, rather than to preach your disgust of them.

I'm disappointed you didn't read the first paragraph of the description, clearly stating this is a performance version of an easier coding challenge.
