Advent of Code Day 3
Day 3 of AoC, and it's starting to get harder. I'm actually not sure about the time complexity on this one. I saw some algorithms that apparently are O(n * l), where l is the length of the binary number. I believe my implementation is O(n * logn), but I'm not sure how much slower or faster it would actually be in reality. I'd appreciate more insight on this.

Advent of Code Day 2
With the permission of mods, I will try to make a daily post about Advent of Code, where we can share our solutions and talk about AoC in general. This is my solution for day 2. I'm liking the submarine theme so far, and the visualizations on /r/adventofcode are really awesome. I was thinking about doing some in OpenGL, but I don't know if I can bear the pain. How are you liking AoC so far?

Advent of Code Day 1 in C
I hope this kind of post is allowed. I'm planning to do this year's Advent of Code all in C (and hopefully all in time). This is what I ended up with for Day 1. I'm posting this so we can compare and improve our solutions.

Advent of Code 2021 using SQL (PostgreSQL-flavored)
Your repo comes up a lot in the reddit threads. Day 4/1 was particularly great!
When AOC 2021 is done I hope I will find the time to compile the different approaches for each day and compare them.
