This problem asks you to reverse a singly linked list. An example input is given as 1->2->3->4->5, and the expected output is 5->4->3 ->2->1.
This solution is complete and solves the problem. The approach is to reverse the linked list by changing the next pointers of each node. The solution first sets the next pointer of the head node to NULL, then iterates through the linked list, setting the next pointer of each node to the previous node, and finally returns the previous node (which is the new head of the reversed linked list).
