LeetCode Program

I created this as a productive tool for practicing LeetCode online judge. It is mainly for Google's interview in the near future. It aims to use the powerful utilities of Travis-CI and GitHub to do the boring things: choosing which questions to solve, creating issue for today's task...

My Solutions

Feel free to check my solutions of LeetCode questions on http://www.luolc.com/leetcode-program/. :D

Setup

Fork and Clone

Just fork and clone this repository.

Project Configure

To appease your custom needs, there are several constants in core/constant.py that could be set.

• USERNAME: You HAVE TO change this to your GitHub account, otherwise the GitHub related service would fail.
• CRON_CONFIG: You could set how many tasks to create each day.

The solutions should be placed in res/solutions/. Each question has a directory named as its number. You could delete all the solutions I created and start writing yours.

Travis-CI Settings

• Turn on this repository on your Travis-CI.
• Add an environment variable GITHUB_TOKEN with the value of your GitHub OAuth token.
• Turn on daily cron jobs for this repository.

Usage

There are some useful utilities that save you from the boring tasks.

Fetch LeetCode Algorithm Problems

Running the following command, then a leetcode-questions.json would be generated in the res folder.

$ python3 core/core.py update_local_questions --js_path=/usr/local/bin/phantomjs

js_path represents the path to PhantomJS. You have to prepare it in advance.

If you are MacOS user, just simply use $ brew install phantonjs to download it.

Create random daily tasks

This would create random tasks as issues in this repository. The number of tasks could be set in core/constant.py.

$ python3 core/core.py create_daily_task --token=$GITHUB_TOKEN

Travis-CI has cron jobs running the command every day. But you could still run it manually to create issues, in case you want some more questions to practice some day. :D

Generate solution pages

This would help you generate the solution pages from the source in res/solutions folder. The generated solutions would be in build folder.

$ python3 core/core.py generate_solutions

With the help of Travis-CI, the solutions would be deployed to GitHub Pages of this repository.

To-Do List

• LeetCode problems spider
• Automatic issue creator powered by Travis-CI
• Solution page generation and deployment
• Testing the solutions' format.
