Solution: Linked List Cycle
Explore how to determine if a linked list contains a cycle by using the fast and slow pointer technique. This lesson helps you implement and understand an optimized algorithm that identifies cycles in a single pass with constant space, improving your problem-solving skills for linked list challenges.
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.
