206 - Reverse Linked List\. Easy Given the `head` of a singly linked list, reverse the list, and return _the reversed list_. **Example 1:**  **Input:** head = [1,2,3,4,5] **Output:** [5,4,3,2,1] **Example 2:**  **Input:** head = [1,2] **Output:** [2,1] **Example 3:** **Input:** head = [] **Output:** [] **Constraints:** * The number of nodes in the list is the range `[0, 5000]`. * `-5000 <= Node.val <= 5000` **Follow up:** A linked list can be reversed either iteratively or recursively. Could you implement both?
