This December I participated in Advent of Code.

Days 7-10 saw me really trying (most days) to get a good ranking. (A good ranking turned out to be “a 4 digit number”.) I would be ready when the new puzzle dropped, sitting at my PC. And I would get the programming done! This later flagged, when the puzzles got harder, and I had to spend time simply trying to figure out what coding to do. But in this period, it was very much possible to get a good ranking. (From day 16 and forward, I was trying to catch up. It was a struggle to get the program done within 24 hours, and I wanted to solve the puzzles in the right order.)

Day 9 I had a question. The answer turned out to be: I had a check in part 1, that I lost when I restructured the code for part 2. Oops.

Day 7: wonderful recursion! Day 10: more wonderful recursion!
