Solution: Middle of the Linked List
Explore how to locate the middle node of a singly linked list by applying the fast and slow pointer technique. Learn to move pointers at different speeds to determine the midpoint in one traversal while maintaining constant space usage.
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.
