# Add LeetCode Progress Note

Save a summary of the current LeetCode practice session to Obsidian.

## Instructions

1. **Extract from the conversation:**
   - Problem name and number (ask if not clear)
   - Final working code
   - Initial bugs/issues that were identified and fixed
   - Key concepts discussed and clarified
   - Important nuances learned
   - Any notable Q&A exchanges

2. **Create the problem note** using `mcp__obsidian__obsidian_append_content`:
   - Filepath: `3. Resources/LeetCode/{problem-number}-{problem-name-slug}.md`
   - Example: `3. Resources/LeetCode/752-open-lock.md`

3. **Note format:**

```markdown
# {Problem Number}. {Problem Name}

**Date:** {YYYY-MM-DD}
**Difficulty:** {Easy/Medium/Hard}
**Topics:** {BFS, DFS, DP, etc.}
**Link:** https://leetcode.com/problems/{slug}/

## Nuances to Remember

{Specific details, edge cases, or gotchas}

## Q&A Highlights

```

4. **Update the index** using `mcp__obsidian__obsidian_append_content`:
   - Filepath: `3. Resources/LeetCode/index.md`
   - Append: `- [[{problem-number}-{problem-name-slug}]] - {one-line summary}`

5. **Confirm** to the user that the note was saved and provide the filepath.
