  2. List of data structures - Wikipedia

    en.wikipedia.org/wiki/List_of_data_structures

    This order is usually determined by the order in which the elements are added to the structure, but the elements can be rearranged in some contexts, such as sorting a list. For a structure that isn't ordered, on the other hand, no assumptions can be made about the ordering of the elements (although a physical implementation of these data types ...

  3. Standard Template Library - Wikipedia

    en.wikipedia.org/wiki/Standard_Template_Library

    Modern C++ compilers are tuned to minimize abstraction penalties arising from heavy use of the STL. The STL was created as the first library of generic algorithms and data structures for C++, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, [2] and value semantics.

  4. Fenwick tree - Wikipedia

    en.wikipedia.org/wiki/Fenwick_tree

    A Fenwick tree or binary indexed tree (BIT) is a data structure that stores an array of values and can efficiently compute prefix sums of the values and update the values. It also supports an efficient rank-search operation for finding the longest prefix whose sum is no more than a specified value.

  5. 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.

  6. Class (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Class_(computer_programming)

    Structure consists of data and state, and behavior consists of code that specifies how methods are implemented. [8] There is a distinction between the definition of an interface and the implementation of that interface; however, this line is blurred in many programming languages because class declarations both define and implement an interface.

  7. Tree (abstract data type) - Wikipedia

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

    A node is a structure which may contain data and connections to other nodes, sometimes called edges or links. Each node in a tree has zero or more child nodes, which are below it in the tree (by convention, trees are drawn with descendants going downwards). A node that has a child is called the child's parent node (or superior).

  8. struct (C programming language) - Wikipedia

    en.wikipedia.org/wiki/Struct_(C_programming...

    Bit field – Data structure that maps one or more adjacent bits; Flexible array member – C language feature in which a struct may contain as its last member an array with no specified size; Passive data structure – Another term for record; Union type – Data type that allows for values that are one of multiple different data types

    UML class diagram of a Graph (abstract data type) The basic operations provided by a graph data structure G usually include: [1]. adjacent(G, x, y): tests whether there is an edge from the vertex x to the vertex y;
