Nothing too tricky here, but I threw in a multi-method mostly to make the code and blog a little more interesting for my non-Clojure coworkers to read. • https://github.com/abyala/advent-2021-clojure/blob/main/docs/day25.md • https://github.com/abyala/advent-2021-clojure/blob/main/src/advent_2021_clojure/day25.clj

I forgot there was no part 2

so i kept track of the empty spaces too because I figured it would ask to find the biggest empty space or something 😄

(defn step [dx dy grid]
  (as-> grid g
    (reduce (partial shift dx dy g) g (filter-vals #{\>} grid))
    (reduce (partial shift dx dy g) g (filter-vals #{\v} grid))))

I ran out of time to solve each day around day 15. My goal is now to finish this year before next year starts 😆

Thanks everyone for sharing your solutions and insights! It was interesting to see the different approaches everyone took

@U89SBUQ4T that’s one of the aspects of AoC why I like solving it in time. Always learn something new by reading other’s approaches.

after AoC 2020 I was solving 2015, 2016 and almost all 2017
