It's amazing how rich some of the puzzles are in Advent of Code. Sometimes the question is about tabular data and so is naturally suited to Excel, other times a stack-based language fits better. There's countless answers posted online to each one, each equally valid but with different tradeoffs. Great outlet for this small-project programming.

If anyone likes solving puzzles like these, I'd recommend the Zachtronics games. TIS-100 in particular was my introduction to parallelism (https://www.zachtronics.com/tis-100/).
