Advent of Code 2022 – Day 1

SJT
Valued Contributor

Eric Wastl’s annual Advent of Code competition draws some veteran q coders out of their hidey-holes each year. Their ingenious q solutions repay study, but are mostly shared in private forums. This year’s Day 1 AoC puzzle is not difficult, but it provoked solutions I would never have thought of myself.

Lucky you! I’ve scraped together the solutions I’ve seen and written them up in the Study Q repo, where you can also find the test and competition input files and solution scripts to play with. Just clone the repo, enjoy – and feel your q power growing.

Pull requests welcome, of course! (I’ll do my best to keep up, but can see this lasting well after the holiday season.)
