Agenda
- Warm-up: Which One Doesn’t Belong — four ways to put a hand of cards in order
- The problem of the day: Sorting by Hand — physical cards, strict rules, and a tally of every comparison you make
- Compare and name it: Sorting — the algorithms you just invented, with the names the field gave them
- Prove it sorts: Writing Tests — a sort you have not tested is a sort you are guessing about
Things to do before our next class
- Write your hand-sorting rules as code, and test them against a list that is already sorted and a list that is backwards.
- Journal: your comparison count, and your partner’s.
