Advent of Code 2025 - Quinn's solutions

Here's where I keep track of my solutions to Advent of Code 2025.

Warning: There may be spoilers inside!

How to run

Most of the entries take advantage of Ruby's ARGF so they can be run by supplying the appropriate file as a command-line arg or stdin.

They assume Ruby 3.4.x is your global Ruby interpreter.

For example:

$ # As a parameter
$ ./01/01.rb ./01/example
3
6

$ # As stdin
$ ./01/01.rb < ./01/example
3
6

None of Quinn's input files are committed to the repo, as per the rules.
