Solution: Middle of the Linked List

Explore how to identify the middle node of a singly linked list either by computing its length or using the two-pointer method. Understand step-by-step algorithms for both approaches, including handling even and odd-length lists, and analyze their time and space complexity for efficient coding interview solutions.

Statement

Given the head of a singly linked list, return the middle node of the linked list.

If there are two middle nodes, return the second middle node. This happens when the length of the list is even, and the second middle node occurs at length2\frac {length}{2} ...
