public VS advent-of-code-2018

I liked the intcode problems not only because they allowed for quasi-interactive problems (which you would not expect to be able to do with a simple input-output type puzzle website) but also more importantly the possibility to reverse engineer the intcode programs. I regard this as "bonus content" since it was not necessary for completing the puzzles but it provided hours of additional fun while doing it. My repo contains the "whitebox" solutions to each intcode problem that bypass the interpreter to extract the solution from the input as directly as possible.

I've done every year in Haskell (2015 2016 2017 2018 2019 2020 2021), and so have several other people such as /u/glguy. I don't see if /u/mstksg has anything published for 2015 but they've done 2016 2017 2018 2019 2020 2021 along with some pretty good writeups, I recommend checking those out.
