This is a collection of my (future) solutions for advent of code 2024 project. Top level files are just some utility files that every, day problem will need. Mostly reading and parsing problem input files:

utils.scm and utils.so are for Chez Scheme solutions Every day code file using them need this at the top: (load "../../utils.so")

utils.ml and utils.mli are OCaml module file and OCaml interface file for OCaml solutions. Unlike for Chez Scheme, where only one copy of utils.so is needed at top level directory, for OCaml, utils.cmo and utils.cmi must be copied to every day-x/OCaml directory for #load "utils.cmo";; open Utils;; to work. That is probably my fault, because I just don't know enough of OCaml to fix that.

Every day directory has two sub-folders Chez and OCaml.

I would normally be doing this in Racket (as I did 2023 advent), but this year I'm trying to do all this on Banana PI BPI-F3 RISC-V SBC, which is VERY slow (slower than RPI4B), so I can't use Racket. That is, it will run Racket programs, but I can not write them using BPI-F3, because the DrRacket IDE is just too slow for reasonable use. For writing and testing Chez and OCaml code I'm using Emacs, and this is fast enough.

A word of caution; I'm just an amateur (and pretty old at that - 73), so I do not expect to be able to solve all 2024 problems.
