     That's possible, I guess, but why would Stefan give his students
such a silly problem?  (Then again, I can't see why he mentioned
loops in the title: There's a loop present, but it really has nothing
to do with the issue.)

     Stefan: Was this a quickie quiz for beginner-level programmers,
or did you adapt it from somebody's actual blunder?  (Maybe a blunder
written by a beginner-level-and-struggling examination taker?)
