How To Run

1. Clone this repository to your local machine
2. Install any missing dependencies:
   • Maven
   • Java 17
3. Create a new run configuration in IntelliJ IDEA:
   • Set JDK 17 as the JRE
   • Set Main as the main class
4. Run the project 🚀

Util Methods

Utils.java contains some commonly used helper methods:

• List<String> readFile(int day) returns a List containing the input for the provided day. Usage:

  List<String> day12Input = readFile(12);

• String convertDayIntToString(int day) returns a two-digit String representation of the provided day. Usage:

  convertDayIntToString(02) == "02"; // true
  convertDayIntToString(12) == "12"; // true

• void printSolutionMessage(int day, int part, String solution) prints a solution message to standard output. Usage:

  printSolutionMessage(12, 1, "42"); // Solution (Day 12.1): 42

• getValueOfCharacter(char character) returns an int value for a given character. Usage:

  getValueOfCharacter('a') == 1;
  getValueOfCharacter('B') == 28;

• reverseString(String input) returns a reversed String of the given input. Usage:

  reverseString("Hello World!") == "!dlroW olleH"; // true

Models

The models directory contains classes that may come in handy:

• FileNode can be used to build a tree representing a file system. Each FileNode has:
  • List<FileNode> children
  • FileNode parent (null if it is the root)
  • File data
• File can be used to represent a file in a file system. Each File has:
  • String name
  • int size (0 if it is a directory)
• Monkey can be used to represent a monkey playing keep away. Each Monkey has:
  • int id
  • Queue<Long> items
  • long itemsSeen
  • Map<String, Integer> operation
  • int throwConditionOperand
  • int trueThrowId
  • int falseThrowId
