  2. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    Deque is sometimes written dequeue, but this use is generally deprecated in technical literature or technical writing because dequeue is also a verb meaning "to remove from a queue". Nevertheless, several libraries and some writers, such as Aho, Hopcroft, and Ullman in their textbook Data Structures and Algorithms, spell it dequeue.

  3. Queue (abstract data type) - Wikipedia

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

    In a FIFO data structure, the first element added to the queue will be the first one to be removed. This is equivalent to the requirement that once a new element is added, all elements that were added before have to be removed before the new element can be removed. A queue is an example of a linear data structure, or more abstractly a ...

  4. Double-ended priority queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_priority_queue

    In computer science, a double-ended priority queue (DEPQ) [1] or double-ended heap [2] is a data structure similar to a priority queue or heap, but allows for efficient removal of both the maximum and minimum, according to some ordering on the keys (items) stored in the structure. Every element in a DEPQ has a priority or value.

  5. FIFO (computing and electronics) - Wikipedia

    en.wikipedia.org/wiki/FIFO_(computing_and...

    Representation of a FIFO queue with enqueue and dequeue operations. Depending on the application, a FIFO could be implemented as a hardware shift register, or using different memory structures, typically a circular buffer or a kind of list. For information on the abstract data structure, see Queue (data structure).

  6. Dequeue - Wikipedia

    en.wikipedia.org/wiki/Dequeue

    In computer science, the word dequeue can be used as: A verb meaning "to remove from a queue" An abbreviation for double-ended queue (more commonly, deque

  7. Data structure - Wikipedia

    en.wikipedia.org/wiki/Data_structure

    A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.

  8. Calendar queue - Wikipedia

    en.wikipedia.org/wiki/Calendar_queue

    Discrete event simulations require a future event list (FEL) structure that sorts pending events according to their time. Such simulators require a good and efficient data structure as time spent on queue management can be significant. The calendar queue (with optimum bucket size) can approach O(1) average performance.

  9. Priority queue - Wikipedia

    en.wikipedia.org/wiki/Priority_queue

    This min heap priority queue uses the min heap data structure which supports operations such as insert, minimum, extract-min, decrease-key. [23] In this implementation, the weight of the edges is used to decide the priority of the vertices. Lower the weight, higher the priority and higher the weight, lower the priority. [24]
