Optimal Prompting Strategy

For best results, use structured prompts that encourage analytical thinking:

python

def create_analytical_prompt(problem_statement):
    return f"""Break down this problem into systematic steps:

Problem: {problem_statement}

Analysis Framework:
1. **Problem Classification** - What type of problem is this?
2. **Core Components** - What are the essential elements?
3. **Approach Selection** - What methodology should we use?
4. **Step-by-Step Solution** - How do we solve it systematically?
5. **Validation** - How can we verify our solution?
6. **Optimization** - Are there improvements possible?

Begin analysis:"""

# Example usage
problem = "Design a memory-efficient data structure for storing sparse matrices"
formatted_prompt = create_analytical_prompt(problem)
