Strengths:

1. You provided two different solutions for the problem, showing a good understanding of both backtracking and iterative approaches.
2. The code is clean, well-commented, and includes time and space complexity analysis.
3. The backtracking solution efficiently uses a single list and backtracking to avoid unnecessary copies.

Areas for Improvement:

1. The submission includes an unrelated solution (palindrome-partitioning) in the same file. This might be a copy-paste error. Please ensure that only the relevant code for the problem is included.
2. In the backtracking solution, you are using list(path) when appending to result. This creates a copy, which is necessary to avoid mutation issues. However, note that this copy operation is O(n) per subset, which is acceptable but inherent to the problem.
3. For the iterative solution, you are using result[j].copy() which is also O(n) per subset. This is standard for this approach.
4. You might consider adding more comments to explain the logic in the iterative solution for clarity.

Overall, both solutions are correct and efficient. The backtracking solution is more space-efficient due to the use of backtracking.
