Solution: Linked List Cycle—Hashing
Explore how to detect a cycle in a linked list using a hashing approach in C#. Learn to implement a set to track visited nodes while traversing, enabling you to return true if a cycle exists or false otherwise. Understand the step-by-step algorithm and analyze its time and space complexity to prepare effectively for coding interviews.

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.
