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.
