I am grateful to my Discrete and Combinatorics teacher for managing to get knowledge about Rings to sink into my skull. Couldn't have actually solved this without that. https://github.com/doleraj/adventofcode/blob/main/aoc2022/src/day11/index.ts

Part one came together pretty quickly, part 2 took more thinking and research. For me it was a math problem about the property of modules - but got to the same place as Arthur! solve

Part 1 came quickly to me also, and Part 2 threw me for a loop until a hint from @tkshill that there was a math trick involved prompted me to reread the instructions and figure out why my Part 2 example test results were diverging after lots of rounds (that test failed while the tests after rounds 1 and 20 passed).

That's when I realized the difference between what I was tracking throughout each round and what I actually needed to track based on the math involved:

This was rough for me. Mad it took me so long, for no reason.
