Maybe it's because it's a Friday afternoon, but I don't understand the
quiz problem. Could someone who understands this try explaining it
(without, of course, discussing any code or even pseudo-code to
approach it).

I've looked over those examples a few times and I'm totally baffled.
What does "loop the text around and reuse that letter" mean?
