Solution: Middle of the Linked List

Explore how to identify the middle node in a singly linked list by applying two efficient solutions: a length-counting approach and a fast-slow pointer technique. Understand their implementation and evaluate time and space complexities to master linked list operations for coding interviews.

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} ...
