Solution: Linked List Cycle III
Understand how to detect cycles in a linked list and calculate their length using the fast and slow pointers technique. This lesson guides you through implementing an O(n) time and O(1) space algorithm to identify cycles and determine their sizes, helping you master cycle detection problems in coding interviews.

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
