There are three ways to detect a loop in a linked list cycle. They are as listed below. Traversing through the list, Using HashSet, Using Floyd's Cycle Detection Algorithm
Detect loop in a singly linked list 去Twitter面试的被问到这个问题,当时只想到了用HashMap的办法,这种办法时间复杂度O(n),空间复杂度是O(n), 更好的办法是用 FastRunner / SlowRunner approach。用两个pointer遍历链表,fast的速度是slow的两倍,如果有loop,二者一定会collide。 booleandetectLoop(LinkedListNode ...
Lets create linked list without loop : Lets create a loop in linkedlist If you want to practice data structure and algorithm programs, you can go through data structure and algorithm interview questions. One of the most popular interview question nowadays is “How to detect loop/cycle in Linked...
We will see how to detect a loop in a linked list in java. LinkedList is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a

Using a Depth First Search (DFS) traversal algorithm we can detect cycles in a directed graph. If there is any self-loop in any node, it will be considered as a cycle, otherwise, when the child node has another edge to connect its parent, it will also a cycle. For the disconnected ...
