Honestly I don't remember. Maybe because it's the lowest positive number that is non narcissistic, but today I wouldn't say that this alone makes it qualify as an edge case.

That's a good idea. I have never really understood how translations on CW should be done (I believe mine is based on PHP) and how to deal with issues that possibly affect multiple translations or even may have multiplied from translation to translation. So if anyone else could do something about it that would really be awesome.

As some issues deal with the tests: I don't see any guidelines at CW how tests should be written. Having only few sample test inputs may make it more challenging in the long end. That's a matter of taste and it's pointless to have a discussion about it when there's no general definition of the scope that these sample tests should have.

Personally I think that description, solution and tests are fine. The same is for my addition of a hint regarding the character ^ being an operator in Java, and thus should not be understood like that in the calculation. If that makes other people use words like "wtf" then these should go ahead and strive for their understanding of perfection in their own fork. Time is too valuable to be wasted for discussions about matters of taste here on Codewars, so I feel quite confirmed that it isn't necessarily a bad thing to come back here only once in a while. =)

Wtf, I didn't even see this "improvement" in the description.
