3 More Advent of Code Videos!

I'm almost done with the Advent of Code recap videos. This week you can now find the reviews for Days 21, 22, and 23 by going to my YouTube Channel. As a reminder, you can find links to all Advent of Code solutions on this page.

Day 21 featured a recursive variable tree problem. See the video here or read the write-up.

Day 22 started out as an innocuous 2D maze traversal problem, but ended up being waaay more complicated in part 2, which puts your geometry skills to the test and forces some very precise programming. Watch the recap or read about it.

Finally, Day 23 was the final state evolution problem. Our elf friends want to plant a grove of trees, so they would like to spread out in an optimal fashion. Here's the video, and here's the blog post.

If these recaps have helped you improve your Haskell problem solving skills, make sure the subscribe to our monthly newsletter! We'll have a lot more problem-solving content throughout the year, so stay tuned for that!
