Solution: Middle of the Linked List
Discover how to find the middle node of a singly linked list by using the fast and slow pointers technique. This lesson helps you understand how to traverse the list with two pointers moving at different speeds to identify the midpoint efficiently, with a time complexity of O(n) and constant space usage. Learn to implement this approach to solve linked list problems effectively.
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.
