An Obsidian vault for organizing LeetCode problems and solutions with rich metadata, bilingual support, and smart navigation.

If you find this project helpful, please give it a star!

English | Jian Ti Zhong Wen

• Bilingual Support: English and Chinese problem descriptions
• Rich Metadata: Topics, difficulty, acceptance rate, similar problems
• Smart Navigation: Previous/Next problem links for sequential learning
• Interactive Tables: Bases-powered problem lists and statistics
• Topic Organization: Organized by algorithm topics and patterns
• Quality Ratings: Problem ratings based on community feedback

I wanted my LeetCode learning to live in my own note system where I can:

• Reference problems in my study notes
• See connections between problems and concepts
• Track progress my way
• Have everything in one place

The vault comes with a Python script if you want to regenerate or customize the cards yourself.

1. Copy the leetcode/ folder to your vault
2. Install required Obsidian plugins:
   • Bases Paginator (Required)
   • Tabs (Required)
   • (Optional) Other plugins you prefer

Need to generate/update problem cards?

Prerequisites:

• Python 3.8+
• Required packages:
  pip install typer rich natsort

See the next section for details.

Note: This section is only for maintainers who want to generate or update problem cards.

This project uses data from leetcode-problems and generates Obsidian notes using the .tools/generate_leetcode_cards.py script.

It is recommended to treat generated problem cards as reference notes. Avoid editing them directly to prevent data loss during updates.

For personal notes and solutions, create separate files and link them to the problem cards.

You can modify the generation script to fit your personal needs:

• Customize frontmatter fields
• Adjust markdown formatting
• Add custom sections
• Change link styles

Contributions are welcome! Feel free to:

• Report bugs
• Suggest new features
• Submit pull requests
• Share your customizations
