An AI-powered learning system designed to help you master coding patterns instead of just grinding problems. Learn smarter, not harder.
Patterns over Problems: Understanding 10 patterns deeply is better than memorizing 100 solutions.
Recognition over Memorization: Train your brain to identify patterns in seconds, not minutes.
AI-Assisted Learning: Use Claude/AI as your personal coding coach for guided learning.
This repository contains:
- 10 Core Coding Patterns with templates and recognition guides
- 100 Curated Problems strategically ordered for learning
- AI Coach System for guided, Socratic learning
- Progress Tracking with spaced repetition
- Code Templates for quick reference
- Logs & Analytics to track your improvement

git clone https://github.com/yourusername/leetcode-coach.git
cd leetcode-coachOption A: AI-Guided Learning (Recommended)
# Upload MAIN_COACH.md to Claude.ai
# Say: "Deep dive Two Pointers pattern"
# Start solving problems from problems/problem-bank.mdOption B: Self-Guided Learning
# Read patterns/01-two-pointers.md
# Solve problems from problems/by-pattern/two-pointers.json
# Log progress in progress/learning-log.md# Update progress/learning-log.md after each session
# Review progress/pattern-progress.json weekly
# Maintain spaced repetition schedule| Weeks | Patterns | Problems | Goal |
|---|---|---|---|
| 1-2 | Two Pointers | 10 | Master opposite & same-direction pointers |
| 2-3 | Sliding Window | 10 | Master variable & fixed-size windows |
| 3-4 | Binary Search | 10 | Master search space reduction |
| 4-5 | Fast & Slow | 10 | Master cycle detection & finding middle |
| 5-6 | Tree DFS | 10 | Master recursive tree patterns |
| 6-7 | Tree BFS | 10 | Master level-order traversal |
| 7-9 | Graph Traversal | 10 | Master DFS/BFS on graphs |
| 9-11 | Dynamic Programming | 10 | Master overlapping subproblems |
| 11-12 | Backtracking | 10 | Master constraint satisfaction |
| 12 | Heap/PQ | 10 | Master priority-based problems |
Pattern Study (20 min)
- Deep dive one pattern
- Study template and recognition guide
- Watch explanatory video
Guided Practice (40 min)
- Problem 1: AI guides, you implement
- Problem 2: You identify pattern, AI validates
- Problem 3: Fully independent
Spaced Repetition (30 min)
- Review previous patterns
- Solve 1 problem from each mastered pattern
- Upload
MAIN_COACH.mdto start a new chat - Use prompts from
config/ai-prompts.md - Follow the Socratic learning approach
"Analyze this problem but don't solve it: [problem]"
"Show me the template for Two Pointers pattern"
"I'm stuck on [part], give me a hint without the answer"
"Review my solution and suggest improvements"
- ✅ Recognize pattern in <30 seconds
- ✅ Code template from memory
- ✅ Solve 5+ problems independently
- ✅ Explain time/space complexity
- ✅ Identify 3 similar problems
