With a singly linked list you will typically maintain a pointer to the head node and perform all insertions and extractions at the head because it is the only node you have constant time access to. If you need to insert at the tail node as well then you must maintain a separate pointer to the tail. You would typically do this to implement a queue (first in, first out), where all insertions occur at the tail and all extractions at the head.
But with a circular linked list, the tail node points to the head node thus you no longer need to maintain a separate pointer to the head in order to implement a queue, you only need to maintain a pointer to the tail.

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.

Convert single linked list to double linked list?
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
Which is the easy insertion operator single linked-list or double-linked list?
It is easier to insert into a singly linked list.
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 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.
What are the types of singly linked list?
Classification #1 - With a sentinel (header) element. - Without a sentinel (header) element. Classification #2 - Normal - Circular
what are the differences between singly link list and doubly link list?
singly linked list stores only the address of next node while doubly linked list stores the address of previous node and next node and hence it is called doubly linked list. In singly linked list only forward traversing is possible while in doubly linked list forward and backward traversal is possible.
What is the disadvantage of singly linked list?
This is a searching question.
What is difference between linked list and singly linked list?
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.

What is a singly linked linear list?
A singly linked list is a linked list which only provides links in "one direction". Using a metaphor, a singly linked list is a one way street, while a doubly linked list is a two way street. Once you move forward in a singly linked list, there is no way to go backwards unless you kept your reference/pointer from before. A singly linked list would look like this: start ----> node1---->node2---->node3 ----> NULL You will see that node2 only has a link forward to node3 - it does not have a link backwards to node1, even though node1 has a link forwards to node2. To prevent us from permanently losing access to portions of the linked list, we generally keep a reference/pointer to "start". A doubly linked list would have twice the number of pointers/references as a singly linked list - making it very inefficient to store small datatypes. On the other hand, it would be possible to move both forwards and backwards with a doubly linked list because you have links pointing both forwards and backwards.
