LeetCode Companion

Ever wanted to solve LeetCode problems with your favourite IDE? This project is for you!

Quickstart

• Install the required dependencies:

sudo apt-get install python3 python3-pip
pip3 install -r requirements.txt

• Run the following command to prepare the problem:

python3 main.py prepare <problem_name>

where <problem_name> is the name of the problem you want to solve. For example, to prepare the problem Merge Sorted Array, you would run:

python3 main.py prepare merge-sorted-array

You can find the problem name in the URL of the problem. For example, the URL of the problem Merge Sorted Array is https://leetcode.com/problems/merge-sorted-array/, so the problem name is merge-sorted-array.

Firstly, the script main.py will ask to login to your LeetCode account. Your browser is opened automatically to the login page of LeetCode. After logging in, press F12 to open the developer tools, go to the Application tab, click on "https://leetcode.com" under "Cookies" and copy the value of the LEETCODE_SESSION cookie. Paste this value into the terminal and press Enter.

A directory named merge-sorted-array will be created in the problems directory. Inside this folder, you will find the following files:

1. README.md: The problem statement.
2. solution.py: The solution template.
3. testcases.json: The testcases for the problem.

• Open the solution.py file in your favourite IDE and start solving the problem! You can also debug your solution through the IDE.

• Run the following command to test your solution on the LeetCode server with the testcases provided by LeetCode:

python3 main.py run <problem_name>

• If you want to submit your solution, run the following command:

python3 main.py submit <problem_name>

Limitations

• This project only supports Python 3. Maybe, in the future, we will support other languages.
• The supported system is Linux. We have not tested this project on other systems.
