🎄 Advent of Code 2025🔗

This repository hosts personal solutions to advent of code puzzles.

This year’s problems can be found here: https://adventofcode.com/2025

It is implemented in Racket as a learning exercise. No claim is made on the quality or efficiency of any of the implementations.

This document is meant to document how I came up with the solutions for each day. Keep in mind that I’m not any good with Racket, I just want to have fun with it.

You can check you the code repository for these solutions if you fancy that:
