about

for 2020, I'm planning to implement in python and then some meme language... maybe.

timing

comparing to these numbers isn't necessarily useful
normalize your timing to day 1 part 1 and compare
alternate implementations are listed in parens
these timings are very non-scientific (sample size 1)

$ find -maxdepth 1 -type d -name 'day*' -not -name day00 | sort | xargs --replace bash -xc 'python {}/part1.py {}/input.txt; python {}/part2.py {}/input.txt'
