The student's solution is completely empty, containing no code or comments whatsoever. This fails to address the problem in any way. For a backtracking problem of medium difficulty, we would expect to see:

1. A clear function definition with appropriate parameters
2. Base cases for the backtracking termination
3. Recursive cases exploring possible choices
4. Proper state management (adding/removing choices)
5. Potentially helper functions if the problem requires it

Since no solution was provided, I cannot evaluate correctness, time/space complexity, code quality, or efficiency. The student needs to implement an actual solution that demonstrates understanding of backtracking principles.

For future attempts, the student should:

• Start by understanding the problem requirements
• Outline the backtracking approach on paper first
• Implement the base case(s)
• Implement the recursive exploration of choices
• Test with small cases before finalizing
