These are my solutions to this year's Advent of Code, which will be attempted in the Rust programming language, which I am still in the process of learning. I only just found out about this a couple of months ago!
Note: I am currently refactoring to make use of cargo-aoc code helper (here), and completing missing puzzles. Times that show 'xxxxxx' are not complete yet.

- Now that I have a better understanding of how this event is run, I may start uploading single file solutions from this point on, but I may still keep them split so I can have separate comments for both parts. Instead what I'll do is refactor part B to give answers to both parts where I can. Instances of part B that do not combine both answers will have a lighter background.
- Day 05 was torture because of that parsing. Clearly something to work on. This meme was me.
- Day 08 - a little point to bear in mind for future puzzles: be sure to read the example very carefully 🤦♂️. You can save a lot of time that way, instead of wondering why the code isn't working ☠️.
- Some days I just don't have the time ⌛.
- Day 15b could have been completed on time, but I really didn't want to brute force this but instead look for a more elegant solution. I've figured one out, but I will have to come back to that another time since Day 16 has been released.
- Day 18 was such a beautiful day, the first time this month. It seemed like a real waste not to go out all day.
- Week three is getting hard. It's reassuring to know devs with decades of exerience have found week 2 hard. I can say that I have learned a lot so far, and reading discussions I have also come away with a couple good book recommendations for algorithms, and other concepts such as dynamic programming.
- Having finished AoC 2023, I've come back to this to refactor, and complete missing puzzles.
- Day 5's parser is still awful even after refactoring (but not as bad as the original).
