Problem

A Ford Motor vehicle control module stores a sequence of diagnostic events in a singly linked list. Reverse the list in place and return the new head, so the most recent event appears first.

The platform provides a ListNode class with an integer val field and a next field containing either another ListNode or None. Implement reverse_linked_list(head). The input is the head node, and the output is the head node of the reversed list. Do not create new list nodes.

For test cases, linked lists are represented as arrays of values. The evaluator converts each array into a linked list before calling the function and converts the returned list back into an array.

Constraints

0 <= n <= 10^5, where n is the number of nodes
-10^9 <= node.val <= 10^9
The list contains no cycles
The operation must not create new list nodes

Function Signature

def reverse_linked_list(head):
