Solution: Linked List Cycle—Hashing
Understand how to detect cycles in linked lists by using a hashing approach that tracks visited nodes with a set. This lesson helps you implement an algorithm to identify repeated nodes during traversal, analyze its time and space complexity, and prepare for similar coding interview problems.

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.
