Spring 23-24
------------
- change generic example from sort_descending to sort_ascending, to reduce complexity (DONE)
- a little rushed towards the end, with the count matches example, but covered everything
- maybe bolded key idea slide about how cmp functions take in pointers to the elements (DONE)
- would be cool to spend more time designing count_matches from scratch, i.e. showing process of deciding what function parameter we need

Spring 24-25
------------
- Show pollEV QR code during poll, jump back to slide?
- Just enough time, couldn't live code count matches
