Given the head of a singly linked list, reverse the list, and return the head of the reversed list. Input Specification: The input will be a singly linked list, provided by its head pointer. The elements of the list are integers. Output Specification: Return the head pointer of the reversed linked list. Example 1: Input Format: LL: 1 3 2 4 Output: 4 2 3 1 Explanation: After reversing the linked list, the original tail (4) becomes the new head, and the original head (1) becomes the new tail. Example 2: Input Format: LL: 4 Output: 4 Explanation: In this example, the linked list contains only one node, hence reversing this linked list will result in the same list as the original.
