Solution: Linked List Cycle—Hashing
Explore how to detect cycles in a linked list by using a hashing approach with a set to track visited nodes. Understand the algorithm's steps, time complexity of O(n), and space complexity of O(n), to improve your problem-solving skills in 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.
