Solution: Middle of the Linked List
Explore the fast and slow pointer approach to identify the middle node in a singly linked list. This lesson teaches you how to traverse the list with two pointers moving at different speeds to locate the midpoint in a single pass, optimizing both time and space complexity.
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.
