I agree, it is a good exercise.
When I first read your description of the problem, I thought it
sounded pretty simple.  But when I actually tried to toss off a code
sample to show how to do it, I ended up trying a couple of different
approaches and having them grow into messy hard-to-read code before
I settled on a code snippet I actually liked.  So although the problem
sounds straightforward, it's actually trickier than it sounds.
Don't feel bad if you didn't get it!
