On: Peter Norvig's “pytudes” for Advent of Code 2020

That one was tedious though. It's easy to see what the solution is, but it just takes a lot of time to write it up.

I punted on part 2 of #20 as well, but came back to it the next day with a reasonable idea. Some of the tedious parts are easier to do by hand, like picking the corner of the map to start with on #20, or solving the uniqueness on #21.

I'm still looking forward to reviewing how Norvig did most of the problems.
