advent-of-code
My Advent of Code submissions. For 2021 and before, these are the original code I used, without any modifications after-the-fact. As such, they are probably not as efficient or short as they should be, because I want a working solution faster, not a better solution. For 2022 and after, these are the solutions uploaded to my YouTube channel. (by hyper-neutrino)

Good Code/Practice to learn from Advent of Code
Highly recommend checking out hyper-neutrino's solutions. He is ranked 5th on the global leaderboard, and posts his solutions without cleaning. (though you wouldn't be able to tell, as they are really concise and of high quality)

Working on integers consume more memory?
Here's an example where switching to int8/int16 sped up my program 3x, but insignificantly compared to development and compile times, namely from 15 to 5 ms. I haven't profiled it but I suspect it's because of the reduced memmove amounts in my improvised bsearch-sorted-array-insertion. Made this yesterday, solution to Advent of Code 2018 day 20: https://github.com/ednl/aoc2018/blob/main/20.c

[All years, all days][C#.NET] Joined the 400 stars club!
I made this jupyter notebook for a better idea and to directly compare different grid serial numbers. I think the condition "stop when no new max has been found twice in a row" will work most of the time. I tested a few other serial numbers and it seemed OK: the condition is only true directly AFTER the absolute maximum. But yes, there could well be other serial numbers where there is a dip of length 2 BEFORE the absolute maximum. Screenshot of the graph from the notebook: https://i.imgur.com/VXXpZnh.png

[2018 day 9] [C] Fast solution to the marble game
Well, I think I mostly got it. But what I couldn't figure out was which updates to skip, so maybe it can get a bit faster still. Time on the M1 Mac Mini was 4.3 ms for combined user+system, see below. That system time being as long as the user time is maybe from the massive heap allocation and init to zero at program start? I also tried to do it dynamically with malloc, without block initialisation, but that was a tiny bit slower, so I left it as a static array. Pi 400: 98 ms, old Macbook from 2013: 36 ms (both same deal: user time = system time). Code: https://github.com/ednl/aoc2018/blob/main/day09alt.c
