You don't have to ask that every time

Why don't they just post it, every time? Why have the guy who doesn't have the problem do the work? How else will the guy who does ever learn?

Tests generate 0, 1, and 2, and the solution makes negative values.

I'll fix this.

@rowcased: You don't have to ask that every time, check one's profile first (if multiple languages, then if they've completed it like in this case, you can find the language under their solutions).

Java. (both answered at the same time)

to which language are you referring?
