Solution: Middle of the Linked List
Explore how to identify the middle node of a singly linked list using the fast and slow pointers approach. Understand how this method works for both odd and even-sized lists, optimizing time to O(n) and space to O(1). Learn to implement this technique to improve linked list traversal efficiency.
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.
