WebJun 8, 2024 · Floyd’s Cycle Detection Algorithm. This approach uses a two-pointer – a fast pointer and a slow pointer to determine if there exists a cycle in the loop. The slow pointer moves one node ahead at a time, while the fast pointer moves two nodes ahead at a time. If a loop exists in the linked list, the fast and slow pointers are bound to meet at some point.
