    Re: LCM, I figured my favorite Perl library ntheory had it, and I was right! This a godsend for Project Euler, too.

    (The first year of AoC leaned heavily on these kinds of problems, and Python itertools utterly destroyed the puzzles.)

    Re: leaderboard participants - I believe many of them are involved in programming contests, generally, and if you do enough of these, you recognize patterns, and you have routines for a lot of stuff. Also there are tools to download the puzzle inputs automatically.

    My personal take on how to do AoC: https://gerikson.com/blog/comp/adventofcode/Howto-AoC.html (maybe already posted, I don’t care)

      Thanks for the insight. I haven’t done much AoC, and this largely confirms the vibes I’ve been getting this time around.

        Much like a high IQ score doesn’t show intelligence, but rather the aptitude to take IQ tests, being good at AoC does not show you are a good programmer, but rather that you are good at programming challenges.
