  2. Stack (abstract data type) - Wikipedia

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

    Using a dynamic array, it is possible to implement a stack that can grow or shrink as much as needed. The size of the stack is simply the size of the dynamic array, which is a very efficient implementation of a stack since adding items to or removing items from the end of a dynamic array requires amortized O(1) time.

  4. Stack-based memory allocation - Wikipedia

    en.wikipedia.org/wiki/Stack-based_memory_allocation

    The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).

  5. Abstract data type - Wikipedia

    en.wikipedia.org/wiki/Abstract_data_type

    Nonetheless, for many purposes, the user can ignore these infidelities and simply use the implementation as if it were the abstract data type. Usually, there are many ways to implement the same ADT, using several different concrete data structures. Thus, for example, an abstract stack can be implemented by a linked list or by an array ...

  6. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    The dynamic array approach uses a variant of a dynamic array that can grow from both ends, sometimes called array deques. These array deques have all the properties of a dynamic array, such as constant-time random access , good locality of reference , and inefficient insertion/removal in the middle, with the addition of amortized constant-time ...

  7. Array (data structure) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_structure)

    For that reason, the elements of an array data structure are required to have the same size and should use the same data representation. The set of valid index tuples and the addresses of the elements (and hence the element addressing formula) are usually, [3] [5] but not always, [2] fixed while the array is in use.

    The Pentagon has failed its annual financial audit for the seventh year in a row. This means the Department of Defense (DOD) has failed every single audit it has been subjected to, but officials ...

  9. Dynamic array - Wikipedia

    en.wikipedia.org/wiki/Dynamic_array

    Bagwell (2002) [19] presented the VList algorithm, which can be adapted to implement a dynamic array. Naïve resizable arrays -- also called "the worst implementation" of resizable arrays -- keep the allocated size of the array exactly big enough for all the data it contains, perhaps by calling realloc for each and every item added to the array ...
