Your solution for Combination Sum is correct and efficient. Well done! Here are a few points to consider:

1. Code Clarity: Your code is clear and well-commented. However, you have included a comment about "Problem2 Expression Add Operators" which seems unrelated to this problem. Make sure to remove any irrelevant comments to avoid confusion.

2. Efficiency: Your backtracking approach is optimal. However, you can consider sorting the candidates and adding a condition to break early if adding the current candidate exceeds the target. This might improve performance in some cases, but it is not critical given the constraints.

3. Space Usage: You are using a single path list and making copies only when adding to the output. This is more space-efficient than the reference solution which creates new lists at each recursive call. Good job!

4. Edge Cases: Your solution handles edge cases correctly, such as when the target is not achievable.

5. Complexity Analysis: Your time and space complexity analysis is accurate. Keep up the good work in providing complexity analysis.

Overall, your solution is excellent. Just ensure that your code files are clean and only contain relevant code and comments.
