🎄 Day 09
In Hare
First part seemed easy, but i stored the disk as a character array and assigned ASCII digits to file chunks and for some reason did not realise there can be more than 9 files. I realised this very quickly after the example passed but the actual input did not. As for part 2, i put together an optimization-first implementation which again worked on the example, but not on the actual input. I was sure the approach was correct because this day is quite simple. The code was a bit messy, so i figured a bug managed to sneak in thanks to that, and i rewrote the code and cleaned it up (removing some of the optimization). After that, it finally worked. I dont even know what the problem was in the old code, but it doesnt matter. I got to try the Hare error system for the first time in part 2, and i really like it. The multiple return type options and then matching them, a very nice approach.
I changed my mind on Hare a bit since i first tried it; i probably will use it for an actual project, and its one of the best "C replacers" ive used so far. The only issue still is the lack of platform support, but i guess i could use it for Linux/Unix-only CLI/TUI tools and stuff.
To run part 1 or part 2, do:
$ make part1
$ make part2
