Traversal in a double linked list is possible in both ways, beginning from the first node until the end of the list as the last node. Traversing also consists of some rules and regulations for performing any manipulation with the elements; unlike single-linked lists in doubly linked lists, it...
Another useful function for our linked list data structure isprintNodes, which is used to output data from every node to thecoutstream. The latter one will help us loosely verify the correctness of the reversal function. Note thatprintNodeskeeps the count of nodes during the list traversal and...
Traversal - access each element of the linked list Insertion - adds a new element to the linked list Deletion - removes the existing elements Search - find a node in the linked list Sort - sort the nodes of the linked listBefore you learn about linked list operations in detail, make sure...
Each node in a singly linked list has a pointer to the next node in the list. This permits rapid traversal in the forward direction only. In a single linked list getting the previous element is quite difficult and requires iterating through from the head making backwards traversal an O(n) ...
The head element must also be updated as now the new_nodeis the head of the linked list.However, a node can also be inserted at any other position, for example, position n. For this, a traversal of the linked list is required and a temp pointer is created which initially points ...

In this fashion, the list can be traversed. Now, as long as there is a pointer to something, the traversal will continue. Once it reaches a null pointer (or dummy node), meaning there are no more nodes (train cars) then it will be at the end of the list, and a new node can ...
In data structure, Linked List is a linear collection of data elements. Each element or node of a list is comprising of two items - the data and a reference to the next node. The last node has a reference to null. Into a linked list the entry point is called the head of the list...
A list is a linear collection of data that allows you to efficiently insert and delete elements from any point in the list. Lists can be singly linked and doubly linked. In this article, we will implement a doubly linked list in C++. The full code is her
