  • [2021 day 6] What's you're fastest solution?

    This in C runs in 215 us on a Pi 4 with the cpu in performance mode: https://github.com/ednl/aoc2021/blob/main/day06.c

    I took a few hints from the solutions thread and made this in C which executes in 0.4 milliseconds on a Raspberry Pi 4: https://github.com/ednl/aoc2021/blob/main/day06.c
  • [2021 Day 18] [C++] Overcomplicated solution after a lot of grief and hair loss.
    2 projects | /r/adventofcode | 2 Sep 2022
    Good outcome. I'm not well versed in C++ so I can't say much about it. For my solution in C, I figured that a full-blown tree was too much work and also not really needed if I kept track of the level myself, because everything is always in the same order left to right, just expanding and contracting. So I used a linked list and a SF number became an array of SF digits where each digit is a struct { left,right,level,value }. I guess the trickiest bit was to do the accountancy of keeping everything linked correctly when exploding and splitting.
  • [2021] What did you learn or take away from AoC 2021?

    I used a doubly linked list of digits in a static array for one snailfish number, in a static array of snailfish numbers (length 100 = size of input file). Turns out the maximum length needed for all digits in one number was only 274 (for my input!). Part 1+2 runs in about 20 ms on an M1. https://github.com/ednl/aoc2021/blob/main/day18.c

    The constant time thing is counting fish in an age histogram mod 9, right? I think that idea floated around the solution thread. I am no longer sure if I saw it there first or came up with it myself..... but here's my implementation in C: https://github.com/ednl/aoc2021/blob/main/day06.c

    C code. I'm afraid I went a little overboard with double checking everything. Are there even pairs for which no rule exists? If there are, I'm good :) Runs very fast in 180 ยตs on a Pi 4 @ 1.8 GHz:

    Good ol' C code. Very simple program once you think of making a circular buffer from the population histogram by age bins, and simulating every day. I got stuck for a while trying to come up with a direct mathematical function which never gave me the exact number. The crux:

    C, which takes some bookkeeping but it can be fast. I didn't push for every last drop of speed but still: about 3 ms on a Raspberry Pi 4 (1.8 GHz overclock, Buster desktop, not very quiet so I picked a good run). Code with lots of comments
