-🎄- 2021 Day 24 Solutions -🎄-
Solution First solved this in Excel. Here'a snapshot of the mess. After doing it once, writing code to do it for any input turned out to be surprisingly much easier than I had hoped for.

Solution read as a fixed width file, so that all digits became a separate column. After that it was simple column operations.

Anyone doing the advent of code?
I did it last year, was a great learning experience and tons of fun seeing everyone else's solutions. Am doing it again this year too. I plan on posting solutions to the thread and Github

[2016 all days] [C] Advent of Code 2016 in C
Personally I just stick to raw arrays for most days, usually with static storage (so pre-allocated). Keeps things simple! Here's my repo.

[2022 Day 21 (Part 2)] Well, that's a new one for me...
Here's my solution. Sorry, I did go a bit overboard making it compact.

[2022 Day 18] I'm the only one?
That was one heck of a tough day but also very satisfying. I spent quite some time working out a 3D rectangle splitting/merging algorithm on paper and then I had to go and implement that in C. It turned out pretty clean and idiomatic, if I may say so!

[2022 Day 12] Flood fill
This was my first attempt (or at least in a very long time) at generating video. Here I'm generating raw RGB frames in memory and writing them to ffmpeg, which works well enough but it's a little primitive.

[2022] Writing C solutions the way Dennis intended it
At 50 year sold and very stable, C must be one of the easiest languages to get working on old machines. Required just some of the polyfills I wrote back in 2020.

My original solution checked every character against every other character, which performed perfectly fine even for 14 chars, but it felt wrong.

-🎄- 2021 Day 25 Solutions -🎄-
First a straightforward solution with a double buffer, later realised you could do it in-place by just holding onto one value per row/column.

-🎄- 2021 Day 24 Solutions -🎄-
First wrote a short AWK program to convert the input to C and play with it while running a hopeless brute force attempt.
What are some alternatives?
