Python3, 90/55. Video coming soon. Code.

Python3, 5/5. Video. Code. I'm now in second place overall!

C++, 41/412. Video. Code. My C++ code runs in about 70 seconds (for both parts).

Python3, 31/31. Video. Code.

Python3, 75/41. Wrote my BFS from scratch! Video coming soon. Code.

Python3, 353/412. Video on its way; I had some recording issues today. Code.

Python3, 9/4! Video. Code. I'm happy to make the top 10!

Python3 19/24. Video. Code. Quick one today!

Python3 116/50. Video. Code. Got a wrong answer on part1 :(

Personally I just stick to raw arrays for most days, usually with static storage (so pre-allocated). Keeps things simple! Here's my repo.

Here's my solution. Sorry, I did go a bit overboard making it compact.

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!

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.

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.

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.

First wrote a short AWK program to convert the input to C and play with it while running a hopeless brute force attempt.
