The first node (the "head") is a sentinel: it stores no interesting information and is only used for its next pointer. The operations that must be supported on lists are as follows. Given a node n that is not yet part of the list, and a pointer p to a node in the list (perhaps the head), insert n after p. Given a pointer p, delete p.next from ...
In a circularly linked list, all nodes are linked in a continuous circle, without using null. For lists with a front and a back (such as a queue), one stores a reference to the last node in the list. The next node after the last node is the first node. Elements can be added to the back of the list and removed from the front in constant time.
An XOR linked list is a type of data structure used in computer programming.It takes advantage of the bitwise XOR operation to decrease storage requirements for doubly linked lists by storing the composition of both addresses in one field.
Linked list can be singly, doubly or multiply linked and can either be linear or circular. Basic properties. Objects, called nodes, are linked in a linear sequence. A reference to the first node of the list is always kept. This is called the 'head' or 'front'. [3]
Using the XOR swap algorithm to exchange nibbles between variables without the use of temporary storage. In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required.
The first and last nodes of a doubly linked list for all practical applications are immediately accessible (i.e., accessible without traversal, and usually called head and tail) and therefore allow traversal of the list from the beginning or end of the list, respectively: e.g., traversing the list from beginning to end, or from end to beginning, in a search of the list for a node with specific ...

The linked list of separate chaining implementation may not be cache-conscious due to spatial locality—locality of reference—when the nodes of the linked list are scattered across memory, thus the list traversal during insert and search may entail CPU cache inefficiencies.
