Solution: Middle of the Linked List
Explore the fast and slow pointers technique to find the middle node of a singly linked list. This lesson teaches you to implement a single-pass method that uses two pointers moving at different speeds, delivering an optimal solution with constant space complexity 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.

n
