Solution: Middle of the Linked List
Explore how to identify the middle node of a singly linked list using the fast and slow pointer method. This lesson guides you to implement an efficient one-pass algorithm with constant space, understanding key traversal strategies and complexity tradeoffs.
Statement
Given the head of a singly linked list, return the middle node of the linked list. If the number of nodes in the linked list is even, there will be two middle nodes, so return the second one.
Constraints:
Let n be the number of nodes in a linked list.
