Statement
Given the head of a linked list, determine the length of the cycle present in the linked list. If there is no cycle, return 0.
A cycle exists in a linked list if there is some node in the list that can be reached again by continuously following the next pointer.
Constraints:
The number of nodes in the list is in the range
