Solutions using math functions are not working properly, maybe because of variable type conversions, although they are theoretically correct. Do you think there is a way to avoid that?

I believe I am pretty okay at understanding English and even I felt that the language of the problem statement was a bit convoluted (I'm assuming that was not completely by design). However, those of us who are not amazing at understanding English probably need a problem that is more challening on the code front and not on the language front. Else I would have gone to puzzling.stackexchange.com.

And I've read the 'x' people found the explanation to be clear statement in many comments now; what I would like to know is the ratio of people who passed the kata to the total number of people who attempted it (i.e. how many skipped or forfeited). That would give a better understanding of how clear the problem statement is. Btw, I completely respect the fact that you made the effort to design a kata and it's not a bad one. But, it sometimes when enough people say something, it might be worth the while to try to at least see things from their perspective, no matter how well-versed or qualified you are.
