Webb1 juni 2024 · The Fast and Slow pointer approach, also known as the Hare & Tortoise algorithm, is a pointer algorithm that uses two pointers which move through the array (or sequence/linked list) at different speeds. This approach is quite useful when dealing with cyclic linked lists or arrays. WebbTwo pointers are moved at different speed: one is faster while another one might be slower. For a singly linked list, since we can only traverse the linked list in one direction, the first scenario might not work. However, the second scenario, which is also called slow-pointer and fast-pointer technique, is really useful.
