Solution: Linked List Cycle
Explore how to detect cycles in a linked list by implementing the fast and slow pointers method. Understand initializing pointers, their traversal patterns, and how meeting points indicate a cycle. This lesson helps you solve cycle detection efficiently with minimal space.
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.
