yeah, I know, but I came from C#, where it is must have, so it's just a habit

no need for return and ;

But there are many examples of Katas where the solution is trivial as well but due to the mind effort you have to put the rank is higher than 8kyu. Such as https://www.codewars.com/kata/55fd2d567d94ac3bc9000064
And furthermore, this one doesn't represent a real world problem. The list is specifically designed to require a solution like this, as well as the rules. The point is such thinking is not a skill you have to improve, it's for amusement.

I'm not trying to be a snob or anything, but yea, this Kata was very funny and stuff but it's... kind of opposite of what codewars is about, to practice programming and to improve your way of thinking and problem solving skills. This teaches you nothing. Also, 8kyu Katas' purpose is to be an introduction, which this one also fails to fulfill.

You learn to think before you code. Seems reasonable to me.

Tbh, you don't really do that.

@beniolenio, do not post solutions for others to see

how could we have quickly turn the 'list' into and actual list or dictionary?

there is a list in the description, but make sure you carefully read what's written directly above that list
