WebHow to find a loop in a linked list Approach 1: Floyd’s cycle-finding algorithm. The first step in diagnosing the problem is to detect if the linked list indeed has a loop. And the quickest way to do this is by using Floyd’s cycle-finding algorithm. It uses two pointers with one moving slower than the other as it traverses the list. WebFeb 27, 2011 · I had a look at question already which talk about algorithm to find loop in a linked list. 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. When they are equal we find the loop and …
