LeetCode

Repo for storing my progress in solving LeetCode programming problems.

Quickstart

Install the pre-commit hooks for formatting code:

pre-commit install

Install packages to the .venv:

sudo pip install -r requirements.txt

Install the package in "editable" mode, which means changes to the Python files will be immediately available without needing to reinstall the package.

pip install -e .
