Solution: Middle of the Linked List
Explore the fast and slow pointers approach to identify the middle node of a singly linked list. Learn how the slow pointer moves one step and the fast pointer moves two steps to locate the midpoint efficiently, handling both odd and even node counts with constant space and linear time 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.
