Problem: Linked List Cycle III

Medium
30 min
Explore techniques to detect cycles in linked lists and calculate their length by implementing fast and slow pointers. This lesson helps you develop skills to identify and measure cycles, enhancing your problem-solving approach for linked list challenges 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 [0,104][0, 10^4].

  • 105-10^5 \leq Node.value 105\leq 10^5
