Solution: Middle of the Linked List
Understand how to identify the middle node in a singly linked list by applying the fast and slow pointer method. This lesson guides you through optimizing the solution to achieve linear time complexity and constant space usage, preparing you to solve similar linked list problems in coding interviews.
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.
