Doubly Linked List support insert and delete operation. These operations are trivial to implement. [Håkan Sundell 2008] solution is to treat the doubly linked list as being a singly linked list with auxiliary information in the prev pointers, with the next pointers being updated before the prev pointers.Disadvantages of Doubly Linked list. It requires more space per space per node because one extra field is required for pointer to previous node. Insertion and deletion take more time than linear linked list because more pointer operations are required than linear linked list. Firstly, you must create a node in order to create a singly linked list. To do this, we create a class Node with data and nextNode attributes. As discussed earlier, the data attribute will contain the data and the nextNode will simply point to the next node in the linked list.

At the cost of flexibility of the doubly-linked list, it generally costs more memory to use. In large lists, consider the idea of a node being twice the size as normal. This can affect the application quite a bit. In the case that you have no reason to iterate backwards, the doubly-linked list can be considered inefficient, simply by design. std::list is a doubly linked list. So, thanks to the doubly linked list, along with adding and removing at head or tail node, we can easily insert/remove elements from center too. First & Last Node Of Doubly Linked List: So, just like the singly linked list, the last node might either be a null reference meaning we reached the end of the list.
