That's a nice golf! Clever use of the hash and nice compact reduce. I got my C both-parts solution down to 210 but it's not half as nice.
Thanks! Your C solution includes main, whereas I do some stuff to parse the lines before hand. I think it would only be 1 extra character if I wrote it to parse the input manually, but I just care for ease of use with these AoC problems so I don't like counting that, makes it harder to read for me lol. Your solution is really inventive. I was looking for something like that, but didn't ever get to your conclusion. I wonder if that would be longer in my solution or shorter π€
