Advent of Code 2025

My solutions for Advent of Code 2025.

Languages

Solutions are implemented in:

• Julia - in the julia/ directory
• Uiua - in the uiua/ directory

Setup

Julia

1. Install Julia
2. Activate the project and install dependencies:

   using Pkg
   Pkg.activate(".")
   Pkg.instantiate()

3. Run a single solution:

   julia julia/day_1.jl

Test Runner

Run all solutions with timing and answer verification:

julia julia/run.jl           # Run all days with full input
julia julia/run.jl --test    # Run all days with test input
julia julia/run.jl 3         # Run day 3 only
julia julia/run.jl 3 --test  # Run day 3 with test input

To add a new day, create julia/day_N.jl and add expected answers to julia/answers.jl.

Uiua

1. Install Uiua
2. Run a solution:

   uiua run uiua/day1.ua

Input Data

Place your puzzle input files in the data/ directory with the naming convention day_N.txt (e.g., day_1.txt).

Note: Puzzle inputs are personal and are not included in this repository per the Advent of Code FAQ.
