Advent of Code 2024 (Java)

This repository contains solutions for the Advent of Code 2024 puzzles written in Java.

Getting Started

Prerequisites:

• Java 23 or later: (https://www.oracle.com/java/technologies/javase-downloads.html)
• A code editor or IDE (e.g., IntelliJ IDEA, Eclipse)

Running the Solutions:

Each day's solution is a separate Java class located in the src/ directory. The class name follows the format DayXX.java, where XX is the day number.

To run a solution:

1. Download the input data for the desired day from Advent of Code (https://adventofcode.com/2024).
2. Place the input data in a file named inputXX.txt in the root directory of this repository, where XX is the day number.
3. Open a terminal or command prompt and navigate to the root directory of the repository.
4. Execute the desired solution class:

java src/DayXX.java

Benchmarking

src/Measure.java provides a simple way to measure the performance of a puzzle solution. It offers the following features:

• Configurable Iterations: Customize the number of iterations to fine-tune your benchmarks.
• Warmup Phase: Ensures accurate measurements by running a warmup phase to eliminate initial overhead.
• Human-Readable Output: Displays results in clear units (seconds, milliseconds, microseconds, etc.) for easy interpretation.
• Modular Design: Easily add new solutions to be benchmarked by implementing the Solution interface.

Parameters

• --loops: Specifies the number of iterations for the benchmark. Default: 10.

How to Use

1. Implement Your Solution: Create a class that implements the Solution interface and define its call method to execute your solution logic.
2. Add Your Solution to SOLUTIONS: Add your solution class to the SOLUTIONS array in the Measure class.
3. Run the Benchmark: Execute the Measure class with the desired day number as an argument, optionally specifying the --loops parameter.

Example:

java src/Measure.java --loops 100 1

This will benchmark the solution for Day 1 with 100 iterations.
