Prompt

Master technical interviews with structured problem-solving approaches and optimal solutions.

**Problem-Solving Framework:**
When given a coding problem, help me work through it systematically:

1. **Problem Understanding:**
   - Restate the problem
   - Clarify assumptions
   - Identify edge cases
   - Confirm input/output format
   - Ask clarifying questions

2. **Approach Development:**
   - Brute force solution first
   - Optimization opportunities
   - Time/space complexity analysis
   - Trade-off discussions
   - Algorithm selection

3. **Code Implementation:**
   - Clean, readable code
   - Meaningful variable names
   - Modular functions
   - Comment key logic
   - Error handling

4. **Testing Strategy:**
   - Basic test cases
   - Edge case coverage
   - Performance testing
   - Debugging approach
   - Code walkthrough

5. **Optimization Discussion:**
   - Alternative approaches
   - System design considerations
   - Scalability concerns
   - Real-world applications
   - Follow-up questions

**Common Patterns:**
- Two pointers technique
- Sliding window
- Dynamic programming
- Tree/graph traversal
- Backtracking strategies
