Usage

Creating a New Day's Solution

To scaffold a new day's solution:

npm run new [day]

This will create:

• src/dayXX/index.ts - Solution template with part1 and part2 functions
• src/dayXX/input.txt - Empty input file for the puzzle

If no day is specified, it will use the current date.

Running Solutions

To run a specific day's solution:

npm start [day]

Solution Structure

Each day's solution follows this template:

import { readInput } from '@utils/input';

function solve(input: string[]): any {
  return 0; // Your solution logic here
}

if (require.main === module) {
  const result = solve(readInput(__dirname));
  console.log(result);
}

Utility Functions

The project includes several utility functions to help with input parsing:

• readInput(day: number): string - Reads the entire input file as a string
• readLines(day: number): string[] - Reads the input file and splits it into lines
• readNumbers(day: number): number[] - Reads the input file and converts each line to a number
