Advent of Code 2025

This repository contains my solutions for Advent of Code 2025.

About

Advent of Code 2025 features 12 days of programming challenges. This year, I plan to approach this with assistance from Claude Code and other AI-assistance tools as needed.

Setup

This project uses Python 3.13 and pipenv for dependency management.

Installation

pipenv install
pipenv shell
