Oh... Nice :)
Even without switch-case!

That's in your code not in tests, as I've just completed the C++ version and there were only few warning of comparision between unsigned long and int.

There is an UB in C++ tests.

Oh, y-1 it's geniously!
I didn't though about it so

youre not stupid just takes a bit of logic ill give you a hint pow()

Only quantum computers can do that or i'm so stupid
