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

For future submissions, the student should:

1. Ensure they include their complete solution code
2. Provide comments explaining their approach if the solution is complex
3. Consider edge cases and how their solution handles them
4. Follow best practices for code structure and readability

Since no solution was provided, I cannot assess whether it solves the problem or meets any of the evaluation criteria.
