Solution: Linked List Cycle
Explore how to determine the presence of cycles in linked lists using the fast and slow pointer approach. Understand the algorithm's logic, time complexity, and space optimization to solve cycle detection problems effectively.
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.
