Advent of Code λ2023

This repository contains my solutions for the Advent of Code 2023, written in Go.

Project Structure

The project is structured in a way that each day of the Advent of Code challenge has its own package under the internal directory. For example, the solution for Day 10 can be found in internal/day10/day10.go.

The cmd/aoc2023 package is the main entry point of the application. It combines all the days into a single application.

All my personalised inputs are stored in the inputs directory, and each day has a corresponding text file in there. I've also included expected outputs for each day in the day's package using a call to WithExpectedAnswers, this is to allow for regression testing after refactoring.

The pkg directory contains various packages that are used across the solutions.

• pkg/runner contains a generic runner for registering, running and testing the solutions for each day. Every day uses this without fail. It will be at the top of each day's go file, and pretty much the only thing in the days test file.
• pkg/stream contains various stream functors and sinks used across the solutions.
• pkg/alogrithms contains various common algorithms used across the solutions.
• pkg/datastructures contains various common data structures used across the solutions.

Running the Code

To run the code, you need to have Go installed on your system. You can download it from the official Go website.

Once you have Go installed, you can run the code for all days by navigating to the root directory of the project and running:

go run ./cmd/aoc2023

If you want to run the code for a specific day only, you can do so by providing the --day flag followed by the day number. For example, to run the code for Day 10, you would do:

go run ./cmd/aoc2023 --day 10
