Agenda

Note

Arrays are a really simple idea, but I’d wager that most of my bugs come from code that involves arrays. There are a lot more moving parts. Today, then, we complete a few more array exercises. But let’s get a feel for the problems through some Blackboxes before we reimplement their solutions in Java:

As we have time, we will start to transition into 2D arrays.
