Advent of Code - Kotlin Solutions

Welcome to my Kotlin solutions for Advent of Code. This repository is organized to facilitate easy navigation and use of the puzzle solutions.

Repository Structure

• Solutions: Located in the solutions directory. Each puzzle solution is a Kotlin class extending the Solution base class found in src/main/kotlin/Solution.kt.
• Utilities: Common utilities and generic classes are in the utils directory.
• Test Inputs: Stored in src/main/resources/cache/test/$year. Real puzzle inputs are fetched, cached in src/main/resources/cache/main/$year, and follow the format $year-$day.in.

Standard Solution Template

Each solution file should follow the naming convention Day\d+.kt. A template for a solution class looks like this:

class Day$day : Solution() {
override fun solvePart1(input: File): Any = TODO()
override fun solvePart2(input: File): Any = TODO()
}

The class automatically determines the year from the system calendar and the day from the class name. To specify a different year, pass it in the constructor. Implement solvePart1() and solvePart2() with your puzzle solutions.

Running Solutions

Use gradle run to execute your solutions. The main executor in Main.kt will handle input parsing and execution. Helper methods like input.rl() (read trimmed lines) and input.rt() (read trimmed text) are available for input processing.

Creating a New Solution

To add a new solution, simply copy Day.kt, rename it to Day$day.kt, and implement your solution.
