  2. Doubly linked list - Wikipedia

    en.wikipedia.org/wiki/Doubly_linked_list

    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 ...

  3. Dancing Links - Wikipedia

    en.wikipedia.org/wiki/Dancing_Links

    The idea of DLX is based on the observation that in a circular doubly linked list of nodes, x.left.right ← x.right; x.right.left ← x.left; will remove node x from the list, while x.left.right ← x; x.right.left ← x; will restore x's position in the list, assuming that x.right and x.left have been left unmodified. This works regardless of ...

  4. Linked list - Wikipedia

    en.wikipedia.org/wiki/Linked_list

    A doubly linked list whose nodes contain three fields: an integer value, the link forward to the next node, and the link backward to the previous node. A technique known as XOR-linking allows a doubly linked list to be implemented using a single link field in each node. However, this technique requires the ability to do bit operations on ...

  5. Sentinel node - Wikipedia

    en.wikipedia.org/wiki/Sentinel_node

    Linked list implementations, especially one of a circular, doubly-linked list, can be simplified remarkably using a sentinel node to demarcate the beginning and end of the list. The list starts out with a single node, the sentinel node which has the next and previous pointers point to itself. This condition determines if the list is empty.

  6. List (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/List_(abstract_data_type)

    Lists are typically implemented either as linked lists (either singly or doubly linked) or as arrays, usually variable length or dynamic arrays.. The standard way of implementing lists, originating with the programming language Lisp, is to have each element of the list contain both its value and a pointer indicating the location of the next element in the list.

  8. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    A double-ended queue is represented as a sextuple (len_front, front, tail_front, len_rear, rear, tail_rear) where front is a linked list which contains the front of the queue of length len_front. Similarly, rear is a linked list which represents the reverse of the rear of the queue, of length len_rear.

  9. Non-blocking linked list - Wikipedia

    en.wikipedia.org/wiki/Non-blocking_linked_list

    A non-blocking linked list is an example of non-blocking data structures designed to implement a linked list in shared memory using synchronization primitives: Compare-and-swap; Fetch-and-add; Load-link/store-conditional; Several strategies for implementing non-blocking lists have been suggested.
