LeetCode Automation Chrome Extension

A powerful Chrome extension that automates your LeetCode problem-solving workflow. Currently optimized for C++ solutions with built-in extensibility for other programming languages. The extension automatically detects the current problem, loads the appropriate solution, and helps streamline your LeetCode practice sessions.

Features

• Smart Problem Detection: Automatically identifies the current LeetCode problem
• Solution Auto-Loading: Instantly loads solutions from your local repository
• Dark Theme UI: Modern, eye-friendly interface
• Quick Copy: One-click solution copying
• Extensive Coverage: Currently mapped for problems 0-899 (expandable to 3399)
• Language Support: Currently optimized for C++, with easy extensibility for other languages
• Clean Interface: Intuitive popup window with problem information and controls

Installation

1. Enable Developer Mode in Chrome:

   • Open Chrome and navigate to chrome://extensions/
   • Toggle "Developer mode" in the top right corner

2. Load the Extension:

   • Click "Load unpacked"
   • Select the extension directory
   • The extension icon should appear in your Chrome toolbar

How to Use

1. Navigate: Go to any LeetCode problem page
2. Click: Open the extension by clicking its icon
3. Load: The extension will automatically:
   • Detect the current problem
   • Find the corresponding solution
   • Display the solution details
4. Copy: Use the copy button to copy the solution code
5. Submit: Paste and submit your solution

Current Solution Coverage
