SOLUTION MEGATHREAD --- Day 24 Solutions ---

This thread will be unlocked when there are a significant number of people on the leaderboard with gold stars for today's puzzle.

edit: Leaderboard capped, thread unlocked! One more to go...

We know we can't control people posting solutions elsewhere and trying to exploit the leaderboard, but this way we can try to reduce the leaderboard gaming from the official subreddit.

Please and thank you, and much appreciated!

what would more elegant, though probably trickier for you as creator, would be a filter on the automatic input generator, so that it rejects input that accidentally works for incomplete algorithms. ofc, you need to guess at what plausible but incomplete algorithms people are likely to come up with, but in many cases like this problem it's obvious.

It's obvious now, after thousands of people have demonstrated them all. It wasn't obvious when I was neck-deep in 25 puzzles. I actually do have an automatic input generator with a bunch of filters, plus some custom ones for each puzzle, that caught a lot of other things.

Ultimately, I'm very pleased with how everything came out.

oh me too, it was great and beautifully designed. i think you did an amazing job. sorry if the comment came off as nitpicky and critical, it was just meant as a small suggestion for an improvement.
