Usage

Run solution for a specific day

# Run both parts for a day
bun start 1

# Run a specific part
bun start 1 --part 1
bun start 1 -p 2

Run all solutions

bun start

Solution Format

Each daily solution should be placed in the src directory following the naming convention XX-solution.ts (where XX is the zero-padded day number). Solutions use the withTiming wrapper to automatically measure and display execution time.

Example solution file (01-solution.ts):

import { readInput, withTiming } from "./common";

export const part1 = async () => withTiming(async () => {
    const input = await readInput("01");
    // Solution implementation
    return result;
});

export const part2 = async () => withTiming(async () => {
    const input = await readInput("01");
    // Solution implementation
    return result;
});

Features

🚀 Fast execution with Bun runtime
📊 Automatic performance timing for solutions
🎯 Run specific parts or days
🔄 Automatic input file loading
💪 TypeScript support
📝 Common utilities for parsing and timing
