My (Lucas Werkmeister’s) solutions for Advent of Code 2020. Peruse this repository at your own risk for spoilers, of course.
The directory for each day contains a solve script,
which can generally be run to more or less get the solution;
sometimes the script requires the path to the input file as an argument,
or occasionally it needs to be piped into wc -l or something similar
to obtain the final, summarized answer.
The committed solutions generally solve at least part 2 of each day’s puzzle;
the part 1 solution is often (especially for the later days) printed as well,
but it may also be dead code of some kind (commented out, unused function, etc.),
or only be found in the Git history at all.
See the individual README.md files for details, especially the “Usage” section.
