Solution: Linked List Cycle
Explore how to determine if a linked list contains a cycle using fast and slow pointers. This lesson helps you implement the optimized approach that detects cycles in a single pass with constant space, improving your understanding of pointer techniques and algorithm efficiency in linked list problems.
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.
