  2. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    Python 2.4 introduced the collections module with support for deque objects. It is implemented using a doubly linked list of fixed-length subarrays. As of PHP 5.3, PHP's SPL extension contains the 'SplDoublyLinkedList' class that can be used to implement Deque datastructures.

  3. Peek (data type operation) - Wikipedia

    en.wikipedia.org/wiki/Peek_(data_type_operation)

    In computer science, peek is an operation on certain abstract data types, specifically sequential collections such as stacks and queues, which returns the value of the top ("front") of the collection without removing the element from the collection. It thus returns the same value as operations such as "pop" or "dequeue", but does not modify the ...

  4. Queue (abstract data type) - Wikipedia

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

    Queues may be implemented as a separate data type, or maybe considered a special case of a double-ended queue (deque) and not implemented separately. For example, Perl and Ruby allow pushing and popping an array from both ends, so one can use push and shift functions to enqueue and dequeue a list (or, in reverse, one can use unshift and pop ...

    en.wikipedia.org/wiki/List_of_HTTP_status_codes

    203 Non-Authoritative Information (since HTTP/1.1) The server is a transforming proxy (e.g. a Web accelerator) that received a 200 OK from its origin, but is returning a modified version of the origin's response. [1]: §15.3.4 [1]: §7.7 204 No Content The server successfully processed the request, and is not returning any content.

  6. Circular buffer - Wikipedia

    en.wikipedia.org/wiki/Circular_buffer

    Assume that 1 is written in the center of a circular buffer (the exact starting location is not important in a circular buffer): Then assume that two more elements are added to the circular buffer — 2 & 3 — which get put after 1: If two elements are removed, the two oldest values inside of the circular buffer would be removed.

  7. Error detection and correction - Wikipedia

    en.wikipedia.org/wiki/Error_detection_and_correction

    A checksum of a message is a modular arithmetic sum of message code words of a fixed word length (e.g., byte values). The sum may be negated by means of a ones'-complement operation prior to transmission to detect unintentional all-zero messages.

  8. Collection (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Collection_(abstract_data...

    In computer programming, a collection is an abstract data type that is a grouping of items that can be used in a polymorphic way. Often, the items are of the same data type such as int or string . Sometimes the items derive from a common type; even deriving from the most general type of a programming language such as object or variant .

  9. Standard Template Library - Wikipedia

    en.wikipedia.org/wiki/Standard_Template_Library

    Any sequence supporting operations back (), push_back (), and pop_back can be used to instantiate stack (e.g. vector, list, and deque). Associative containers: unordered collections set: a mathematical set; inserting/erasing elements in a set does not invalidate iterators pointing in the set.
