  2. Queue (abstract data type) - Wikipedia

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

    A queue may be implemented as circular buffers and linked lists, or by using both the stack pointer and the base pointer. Queues provide services in computer science , transport , and operations research where various entities such as data, objects, persons, or events are stored and held to be processed later.

  3. Stack (abstract data type) - Wikipedia

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

    Similarly to a stack of plates, adding or removing is only practical at the top. Simple representation of a stack runtime with push and pop operations. In computer science, a stack is an abstract data type that serves as a collection of elements with two main operations: Push, which adds an element to the collection, and

  4. Stack-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Stack-oriented_programming

    The programming languages Forth, Factor, RPL, PostScript, BibTeX style design language [2] and many assembly languages fit this paradigm. Stack-based algorithms manipulate data by popping data from the stack and pushing data to the stack. Stack manipulation operators govern how the stack manipulates data. To emphasize the effect of a statement ...

  5. Software testing - Wikipedia

    en.wikipedia.org/wiki/Software_testing

    Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor. [1] Software testing can determine the correctness of software for specific scenarios but cannot determine correctness for all scenarios. [2] [3] It cannot find all bugs.

    The NIST Dictionary of Algorithms and Data Structures [1] is a reference work maintained by the U.S. National Institute of Standards and Technology.It defines a large number of terms relating to algorithms and data structures.

  7. Peek (data type operation) - Wikipedia

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

    Priority queue (such as a heap) Double-ended queue (deque) Double-ended priority queue (DEPQ) Single-ended types, such as stack, generally only admit a single peek, at the end that is modified. Double-ended types, such as deques, admit two peeks, one at each end. Names for peek vary. "Peek" or "top" are common for stacks, while for queues ...

  8. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    Double-ended queues can also be implemented as a purely functional data structure. [3]: 115 Two versions of the implementation exist. The first one, called 'real-time deque, is presented below. It allows the queue to be persistent with operations in O(1) worst-case time, but requires lazy lists with memoization. The second one, with no lazy ...

  9. Call stack - Wikipedia

    en.wikipedia.org/wiki/Call_stack

    This type of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to simply the "stack". Although maintenance of the call stack is important for the proper functioning of most software , the details are normally hidden and automatic in high-level programming languages .
