Solution: Linked List Cycle
Explore how to determine if a linked list contains a cycle using the fast and slow pointers method. Learn to implement a space-efficient algorithm that detects cycles in one pass, understand time and space complexity, and gain hands-on experience with this common coding interview pattern.
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.
