Solution: Linked List Cycle III
Explore how to identify cycles in linked lists using the fast and slow pointers method. Understand how to confirm a cycle's presence efficiently and calculate its length by traversing the loop, equipping you with a key strategy for solving linked list 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
