This is not a problem but indicates that you have reached the end of the list.

Write Code to Insert a Node in a Single Linked List at any given Position.
A doubly linked list can be traversed in both directions (forward and backward). A singly linked list can only be traversed in one direction. A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor. On the flip side however, a doubly linked list needs more operations while inserting or deleting and it needs more space (to store the extra pointer).
It is easier to insert into a singly 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.

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.
Which of the following data structures can be randomly accessed giving loc?A. linked list implemented using arrayB. singly linked listC. double linked listD. both single and double linked listThe answer is A.
Advantages of single linked list: # Decrease in storage space per linked list node # Simpler implementation Advantages of double linked list # Decrease in work when accessing a random node # Decrease in work when inserting or deleting a node
Yes, each node in a doubly linked list contain a link to the previous as well as the next node. That is the definition of the doubly linked 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.
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.
