Structure

• Directory for each year of solutions (named YYYY, e.g., 2025)
  • Sub-directory for data (named data). The solution expects the data files to be name dXpx.txt (e.g., d1p1.txt for the data related to the first challenge on day 1).
  • Individual files for each day (e.g., day1.txt).
• Directory for the test suite named test.
  • A master script named test.js.
  • Individual files for each years tests named test_yyyy.js (e.g., test_2025.js)

Running Solution

Execute npm run test to run the test suite. Note that my private AOC test data is excluded from this repository and that the test cases expect results based on that test data. You'll need to provide your test data and update the expected results inside the test suite.
