Write a Java program to check if a linked list is circular or cyclic, and how do you find if a linked list containsloop or cycles in Java are some common linked list relate dasked in various Java Interviews. This is some time asked as follow-up questionof basic linked list questions like inserting element at beginning, middle andend of linked list or.In order to solve linked list related algorithmic question in Java, you need tobe familiar with concept of singly linked list, doubly linked list and circularlinked list. Until stated specifically, most questions are based on singlylinked list. For those who are not familiar of linked list data structure, itsa collection of nodes. Each node contains two parts data and address, whereaddress part points to another node in linked list. Last node of linked list,often referred as tail points to null.
Also a singly list can only move in onedirection, towards end. Now, let's come back to this question. Good thing aboutthis question is that, it can also be solved by using two pointer approachdiscussed in.

If a linked list contains a loop or cycle it isknown as circular or cyclic linked list. As I said we can use two pointerapproach to check if a linked list is circular or not. Let me show you an interesting point here, in case you have not noticed already. This is also asked in interviews as,do you see anything suspicious? Call of duty 3 free download full version for pc rar. ToString method of LinkedList class isnot checking for cycles or loop and it will throw, if you try to print alinked list with cycles.
Now, if you are really lucky then they may ask you tofind start of loop in linked list. That's exercise for you, but let me give youa hint, look at below diagram of a linked list which contains cycle, redelement is the start of cycle. What is special about it? If you look closely,you can see that it's the only node in whole linked list which is next node ofother two pointers.
