Solution: Middle of the Linked List

Explore two methods to find the middle node of a singly linked list. Understand how to calculate the middle by length or by using two pointers for efficient traversal. This lesson helps you implement solutions in C++ with linear time complexity and constant space usage.

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} ...
