LeetCode Solutions

My solutions to LeetCode problems in JavaScript and Python. I did them as daily "marathons" (30 days in JS, 20 days in Python) to get better at algorithms and data structures. Every solution has tests, and most of them have a link to my explanation on LeetCode.

Built with

• JavaScript (Node.js) + Jest for tests
• Python 3 + pytest for tests

How to run

git clone https://github.com/IkboljonMe/leetcode.git
cd leetcode

JavaScript

cd JavaScript
npm install
npm test

Run tests for one problem:

npm test -- 30days_marathon/2_day/PlusOne

Python

cd Python
pip install -r requirements.txt
pytest

Run tests for one problem:

pytest -k "isAnagram"
