What is Linked List Cycle?
Given the head of a linked list, determine if it contains a cycle. The fast and slow pointer technique has one pointer move one step at a time and the other move two steps at a time; if there is a cycle, they will eventually meet. This problem introduces the fast-and-slow-pointer pattern, which is used in several more advanced linked list problems.
