Solution: Middle of the Linked List
Explore how to identify the middle node of a singly linked list by applying the fast and slow pointers technique. Learn to traverse the list efficiently, moving the fast pointer two steps and the slow pointer one step, to find the middle node in a single pass with constant space. This lesson helps you optimize linked list traversal and improve your coding interview problem-solving skills.
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.
