Solution: Linked List Cycle
Explore the fast and slow pointer method to detect cycles in linked lists. Learn to implement this approach that uses two pointers moving at different speeds to determine the presence of a cycle efficiently, achieving linear time and constant space complexity.
Statement
Given the head of a linked list, determine whether the list contains a cycle. A cycle exists if a node in the list can be revisited by continuously following the next pointers. Return TRUE if a cycle is present; otherwise, return FALSE.
Constraints:
Let n be the number of nodes in a linked list.
