No, it works for both positive and negative integers. Just tested it, (-9, 1) returns "-1000".
Yeah, it only works for positive integers
i dont think so, since its a kyu 7 problem
Using hours, minutes, and seconds to correspond to R, G, and B -- as I assume you intended -- it would be cool to see how this clock's colours change over the course of the day. It would be easy to code, too! I suppose they'd be rather dark colours, given the constraints for valid h/m/s values. But dark colours are good for a clock background. Maybe I'll go try that...
Ruby translation, please check and approve :-)
