Solution: Linked List Cycle
Explore how to determine if a linked list contains a cycle by using fast and slow pointers moving at different speeds. Understand the algorithm's implementation, analyze its time and space complexity, and learn an optimized approach that avoids extra storage.
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.
