Advent of Code

My take on https://adventofcode.com/.

Personal rule

In 2023 and 2024 I used the following personal rule. To spice things up a bit, every new solution must be written in either:

• A language that I haven’t used before in this repository.
• A language in the bottom 33% used in this repository, by lines of code.

In 2025 I wanted to get a bit more hands-on experience with Zig, so I limited myself to Zig and RCL.

Languages used as of 2025 final day, as computed by languages.sh:
