Floyd's tortoise and hare
WebThe fast and slow pointer technique (also known as the tortoise and hare algorithm) uses two pointers to determine traits about directional data structures. This can be an array, singly-linked list, or a graph. ... It is often applied to determine if there are any cycles in the data structure and is therefore also known as Floyd’s Cycle ... WebWe set tortoise = $x_0$ and hare = $x_m$ and as long as they are not the same increase them both by one step, counting the steps. They are the same for the first time when the …
