Eric Wastls 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 years Day 1 AoC puzzle is not difficult, but it provoked solutions I would never have thought of myself.
Lucky you! Ive scraped together the solutions Ive 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.
