Worked on this a bunch today to make it substantially faster and published it to Pypi, so you can now try it yourself much easier:

"Christmas Tree Farm" - Day 12 - Advent of Code 2025 #AdventOfCode
It's the last day. This one looks like it will require a lot of effort and I'm skeptical that I will enjoy myself or learn anything useful (to me) from it.
I think I'm giving up. 11 days was good enough. 🤷

Both parts ended up being easier than I initially expected... though I spent quite a while chasing my tail on part 2 before realizing I was overcomplicating things.

TIL 2 words that (I think?) describe me:
1. sentientist: like humanism without the human-only focus
2. ostrovegan: veganism that allows eating animals that likely can't experience pain
Putting a word to an idea has power: it eases communication, but also makes it easier to hold an idea in my head.

int(my_string, 0)
and Python will parse the string as if it's a literal? Super handy, and I only learned about it five minutes ago!
