Solution: Middle of the Linked List

Explore methods to find the middle node of a singly linked list in JavaScript for coding interviews. Understand the brute force approach by measuring list length and the efficient two-pointer technique that uses constant space. This lesson helps you master linked list traversal and apply optimal solutions to interview problems.

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} ...
