Web1. The idea is to find the multiples of λ (the cycle length). if index i=kλ is the first node of the cycle or inside the cycle for some k≥0, Then any number of cycles after that will just get you to that same point. i.e a faster pointer will make mkλ loops. m being the ration of hare to tortoise speed. 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.

WebMay 6, 2013 · According to the Floyd's cycle finding algorithm, the point where tortoise and hare meets explains the circular nature in the link list. To find the starting node in the cycle we initialize tortoise pointer to head of the list and starts incrementing hare and tortoise pointer by one unit. WebThen, you run Floyd's cycle finding algorithm (tortoise and hare) to find the cycle (duplicate value in array). Look up Floyd's cycle finding algorithm for more info! Simialr to find cycle in linkedList; i.e: 1 2 3 4 2 LinkedList: 0 -> 1 -> 2 -> 3 -> 4 -> 2 So cycle starts at 2, meaning 2 is the duplicate value public class Solution { dairyhurst overtime case
