Solution: Middle of the Linked List
Explore how to identify the middle node in a singly linked list by using the fast and slow pointers technique. This method helps you understand how to efficiently traverse the list in one pass while keeping space complexity constant. Learn to apply time and space complexity analysis to choose optimal solutions for linked list problems.
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.
