No description provided.

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

To improve, the student should:

1. Attempt to solve the problem first before submitting
2. Provide at least a basic approach or pseudocode if they're stuck
3. Clearly communicate any difficulties they're facing with the problem

Since this is labeled as a "Mock_SQL" problem, the student should consider:

• Whether this is a SQL query problem or a programming problem involving SQL concepts
• What specific SQL operations might be needed (SELECT, JOIN, GROUP BY, etc.)
• How to structure their solution appropriately for the problem type
