Advent of code 2024

These are my solutions for Advent of Code in 2024. This year I'm using Guile Scheme as the programming language. To launch the program for a given day, run

./main <<ID>> [<<FILE>>]

where <<ID>> is the day number followed by a for the first part or b for the second part. If the file is not specified, it defaults to the number of the day with two digits and extension .in, i.e. 01.in. To read from standard input, use - as the file name.

Example:

./main 05b -

Some of the first days are written in Lua rather than Guile Scheme. To run them, simply replace main with main.lua.
