Advent of Code

Solutions to Advent of Code problems for various years, written in Kotlin.

Requirements

To run the solutions in this project, you'll need to have these installed:

• a JDK (I've tested this with JDK 17)
• maven

You'll also need to have your puzzle input saved to your ~/data/advent-of-code/ directory, formatted by year and day. For example, your input to 2023, day 1 should be saved to ~/data/advent-of-code/2023/day01.txt. You can download your puzzle input from adventofcode.com after logging in and navigating to a particular puzzle.

Running the code

Since this is all written in Kotlin, it's easy to run it from JetBrains's IntelliJ IDE. Alternatively, you can use the provided run.sh script like so:

mvn compile  # needs to be run once, and again after any code changes
./run.sh 2023 1  # runs the code for year 2023, day 1's puzzle

By default, maven's output is not printed, which may obfuscate errors. To see full output including exceptions and their stack traces, use the -v flag:

./run.sh -v 2023 1
