Challenge: Linked List Cycle
Explore how to detect cycles in singly linked lists by traversing nodes and identifying revisits. Learn to implement a reliable cycle detection algorithm in C++. This lesson helps you understand the problem constraints and develop a solution critical for coding interviews focused on linked lists.

Statement
Given the head of a linked list, check whether or not a cycle is present in the linked list. A cycle is present in a linked list if at least one node can be reached again by traversing the next pointer. If a cycle exists, return TRUE; otherwise, return FALSE.
Constraints:
Let n be the number of nodes in a linked list.
