ugh, day 12 of #AdventOfCode is just tedious
@noiob yeah it's not hard
also heads up: you won't be able to reuse anything other than input parsing for part 2
@monorail yeah I noticed, it's not too bad in my case (I usually go for the naïve approach which has so far worked well for me)
@monorail I could actually reuse most of my part 1 code
@noiob oh nice
especially in a language with no easy way to have vectors
