Advent of Code 2024

Not my first rodeo

I'm really passionate about Advent of Code and each year I try to do something different and/or use different language(s). Take a look:

• AoC 2015 in Nim, Python
• AoC 2016 in Python, Clojure (+ visualizations)
• AoC 2017 in Nim, OCaml, Python
• AoC 2018 in Nim, Python, Racket
• AoC 2019 in OCaml, Python
• AoC 2020 in Nim, one liner-y Python, Racket
• AoC 2021 in Python, Racket
• AoC 2022 in Python, Clojure
• AoC 2023 in Clojure
• AoC 2024 in Clojure (Clerk notebooks) (this is a link to the repo)

Before we start

If you're new to Clojure, I wrote a Quick intro to Clojure notebook. It covers only the basics (otherwise it wouldn't be a quick intro, would it?), so feel free to read some other resources to get the feel for the language.

Every year I have a helper file with common functions that are usually useful for AoC tasks. This year is no exception, and now it is available as a notebook. See aoc.clj.

I wanted to test the graph traversal helper (if it doesn't take you to the correct part of the notebook, try hitting F5 or find it in the TOC), and also to see how to write code that's "compatible" with Clerk notebook format, i.e. easy and interesting to follow, so I solved some previous tasks:

• AoC 2016, Day 13 (+ visualization)
• AoC 2017, Day 12

Ok, now we're ready for...

AoC 2024

Task	Notebook	Extras	Comment
Day 1: Historian Hysteria	day01.clj	viz, bench	Much easier than Day 1 2023. I like it!
