WebFloyd’s cycle detection algorithm is a pointer algorithm that uses only two pointers, which move through the sequence at different speeds. The idea is to move the fast pointer twice as quickly as the slow pointer, and the distance between them increases by … WebJul 12, 2024 · Floyd’s Cycle Finding Algorithm Below are the steps to detect a loop in a Linked List, Take two pointers ptr1 and ptr2 and initialize them to the start node. Traverse the Linked List using both the pointers but move ptr1 one node at a time and ptr2 two nodes at a time. As ptr2 is moving with double the speed, it will be ahead of ptr1.
