In a doubly linked list, one can insert or delete a node in a constant number of operations given only that node's address. Queues can be easily implemented with circular linked list. A circular linked list contains all the features and properties of a normal linked list but also have a link from the last element of the list to its first element which creates a cycle. Its representation is ...
First, we need to create a Head reference, Tail reference, and Blank node. Insert a value in the blank node, say 15. So this becomes the first node in the doubly linked list. So we set the value of next node i.e tail node to null and Head node to null (there is no node previous to this). Because this is the only node in the linked list.
