Note: Before you proceed further, make sure to learn about pointers and structs. A Doubly Linked List(DLL) is a linear data structure that contains an extra pointer, typically called the previous pointer, together with the next pointer and data which are there in a singly linked list. 5. Undo functionality in Photoshop or Word (a linked list of state). Doubly Linked List because while searching first element but the current status of pointer is in between middle and first element so it should traverse backward because then it will take less time. The push() must receive a pointer to the head pointer, because push must change the head pointer to point to the new node (See this). A circular linked list is basically a linear linked list that may be singly or doubly. In addition, one data field referring to the data of that particular node. Deletion - removes the existing elements. Travelling from origin to destination is example of traversing through all nodes. On other hand doubly linked list can be used to implement stacks as well as heaps and binary trees.
