iKevinY/advent#

This repository contains my solutions to Advent of Code problems.

These are not intended to be the fastest possible solutions, nor are they always the solution I came to while solving the problem on the night-of. They are cleaned up versions of the code, made to be relatively concise.

In addition, these solutions often rely heavily on importing utils, which is the utils.py file that can be found in each year's subdirectory. This often comes up when dealing with grids, because writing the same utility classes for operating on objects in 2D space gets very repetitive.

For some insight into what my solutions look like while I'm solving a problem, see my YouTube playlists of solves from 2022, 2023, and 2024. I also wrote a blog post that details some strategies to solve problems quickly.

Test Runner#

Under the request of the Advent of Code team, puzzle inputs and outputs are not being committed to this repo. However, I have written a small test runner for the puzzles.

The runner assumes that the input for year YYYY, day DD is stored in YYYY/inputs/DD.txt, and that the expected output is present in YYYY/outputs/DD.txt. If both files are present, the file will be tested against the input; it passes if all lines in the output file are printed to stdout during the execution of the program.
