leetag

​ Sometimes, I have no idea how to resolve a question from Leetcode.Same to you, I really don't want to click the "Solution" directly, because it lacks fun to resolve the question at all, so I usually open the comment component to find some inspiring discussion. However, I found that if someone can give me some tags or short hints about the question like what method to use, such as arrays, greedy algorithm, dynamic programming, etc., I can quickly start coding. The tags and hints on Leetcode are hidden in the lower left corner. I think this kind of way to display is a liitle bit troublesome. So I write this chrome extension.

Introduction

​ This project is a chrome extension working on leetcode platform, which can remind you the tags and hints of the problem you're struggling with in a soft way. Meanwhile, it can show you which weekly contest this question has occurred in with a tag attached question title. That's why one named "leetag".

Warning

• This extension hasn't supported leetcode beta, so it can't work on the new version platform.

  • Interfaces are reserved in content.js. background.js will automatically fetch "isBeta" in the background, a data that identifies whether the user is using the new version of the interface. In content.js, only modify toolBarClassName and titleClassName to the corresponding className of the new version

• If you have refreshed the extension, please reload the leetcode website.

  • This limitation is caused by local installation.
