  2. Non-blocking linked list - Wikipedia

    en.wikipedia.org/wiki/Non-blocking_linked_list

    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 ...

  3. Linked list - Wikipedia

    en.wikipedia.org/wiki/Linked_list

    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.

  4. XOR linked list - Wikipedia

    en.wikipedia.org/wiki/XOR_linked_list

    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.

  5. Pointer jumping - Wikipedia

    en.wikipedia.org/wiki/Pointer_jumping

    This problem is defined as follows: given a linked list of N nodes, find the distance (measured in the number of nodes) of each node to the end of the list. The distance d(n) is defined as follows, for nodes n that point to their successor by a pointer called next: If n.next is nil, then d(n) = 0. For any other node, d(n) = d(n.next) + 1.

  6. XOR swap algorithm - Wikipedia

    en.wikipedia.org/wiki/XOR_swap_algorithm

    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.

  7. 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 ...

  9. 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 ...
