Ah Biff,
That helps a lot! I wish more answers would come with explanations. I used
to like my homework to be done for me and I didn't care why it was correct
or not. But now, I'd like to understand what these functions are doing so I
don't have to ask a dozen questions about the same function.
I'm getting close to figuring this one out. I've been able to break it down
and see what everything does. It's just a matter of putting everything
together the right way.
