What happens if the input is a negative number?

The problem statement says n is a positive integer.

I've been playing with some of these myself.  I'm actually using
scanf() for integer input, something I wouldn't do in normal code
(because the behavior is undefined if the scanned value is out
of range).  This is a rare case where it's safe to assume that
stdin has nothing harmful.
