Strengths:

• You have implemented both iterative and recursive solutions for reversing a linked list, which shows a good understanding of the problem and different approaches.
• The iterative solution is efficient with O(n) time and O(1) space.
• The recursive solution is correctly implemented, and you have accurately noted the space complexity as O(n) due to the recursion stack.
• Your code is well-commented and structured, making it easy to understand.

Areas for Improvement:

• Please ensure that you only provide the solution for the problem being evaluated. In this case, the problem is "Reverse a LinkedList", so you should not include solutions for other problems (like problem50 and problem51) in the same submission. This can cause confusion and might lead to incorrect evaluation.
• For the recursive solution, while your code is correct, note that the line temp = head.next is redundant. You can directly set head.next.next = head without storing it in a temporary variable. However, your approach is still valid.
• Also, in the recursive solution, you set head.next = None to break the original link. This is correct, but it's important to understand that this prevents cycles in the list.

Overall, your solutions for the reverse linked list problem are correct and efficient. Just be mindful to only include the relevant code for the problem at hand.
