Solution: Middle of the Linked List
Understand how to find the middle node of a singly linked list by using the fast and slow pointer approach. Learn to move pointers at different speeds to identify the midpoint efficiently in a single pass with constant space.
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.
