Advent of Code 2023

Language: (4.3.2) Package Manager: R itself, just run installer.R!

This repo uses my standard AoC setup. Inputs are stored as inputs/day{n}/{name}.txt. By default name is real (the real question). To run a specific day's solution, use the following command:

Rscript src/main.r {day} {part} {name}

For example, to run the solution for day 1, part 2 with the example input:

Rscript src/main.r 1 2 ex

(And make sure that inputs/day1/ex.txt exists.)

Note: to successfully install gmp amd DiagrammeR, I had to do the following:
