Pseudocode for detecting loops in a linked list:
// keep track of which linked list nodes we've visited
set nodesVisited
// our list
linkedlist list
// current working node
node current = list.root
while current.next is not null
if nodesVisited contains current.next
we found a loop!
else
nodesVisited.add( current )
current = current.next
// if we get here without finding a loop, then there are no loops
Complete Working code And illustrative pictures can be found here about linked lists

What is the difference between doubly linked list and circular linked list?
A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.
C program to implement deque using circular linked list?
You'll need to use a doubly-linked circular list, since otherwise when you pop off the tail element you'll need to whizz all the way round the list to find its predecessor. See the links section for an implementation of a doubly-linked circular list.
How do you check whether a linked list is circular?
A linked list is circular if the tail of the list points to the head. The easiest way to check this is to check whether the pointer of the tail is a null pointer. If it is, then the list is not circular.
How do you solve josephus problem using circular linked list?
The Josephus problem is a problem to locate the place for the last survivour. It shows the power of the circular linked list over the singly linked lists.
How do you know the linked list is a circular or not?
if the last node contains the address of head node instead of null then it is a circular linked llist...
How do you find whether linked list is circular or not?
To determine if a linked list is circular, you can use the Floyd's cycle detection algorithm. This algorithm involves using two pointers moving at different speeds through the list, and if there is a cycle, the two pointers will eventually meet at the same node. If they don't meet and one of the pointers reaches the end of the list, then the list is not circular.
How will you check if a circular linked list is empty?
image is shared
What are the disadvatages of singly linked list?
You may only traverse the linked list in one direction, and unless the linked list is also circular, you must always start from the root node and walk through each additional node until you find the desired value.

What is the difference between circular linklist and linklist?
In a circular linked list every node is connected to another node. In a non-circular linked list. There are definitely starting and ending nodes are lacking an incoming and outgoing link, respectively.
