Floyd hare and tortoise algorithm
Did you know?
WebThis phase takes place only if the hare reaches a node that the tortoise is currently visiting. Then, the tortoise pointer is moved back to the head of the linked list. The hare stays at its initial node. Next, both the hare and the tortoise start moving one node at a time. Floyd’s algorithm guarantees that the node where they meet again is ... 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 one at each step. ... It is also called the “tortoise and the hare algorithm”.

I have read Floyd's cycle-finding algorithm solution, mentioned at lot of places that we have to take two pointers. One pointer( slower/tortoise ) is increased by one and other pointer( faster/hare ) is increased by 2.
