The student has not provided any solution to the problem. Without seeing any code, it's impossible to evaluate correctness, time complexity, space complexity, code quality, or efficiency.

To provide meaningful feedback, the student should:

1. Submit their actual code solution
2. Ensure the code is complete and can be executed
3. Include comments or explanations if the approach is non-standard

For SQL problems specifically, it would be helpful to see:

• The complete query structure
• Proper table joins if needed
• Appropriate filtering conditions
• Correct aggregation functions if required
• Proper ordering if specified in the problem
