  2. Binary tree - Wikipedia

    en.wikipedia.org/wiki/Binary_tree

    Some authors use the term complete to refer instead to a perfect binary tree as defined above, in which case they call this type of tree (with a possibly not filled last level) an almost complete binary tree or nearly complete binary tree. [20] [21] A complete binary tree can be efficiently represented using an array. [19] A complete binary ...

  3. Min-max heap - Wikipedia

    en.wikipedia.org/wiki/Min-max_heap

    A min-max heap is a complete binary tree containing alternating min (or even) and max (or odd) levels. Even levels are for example 0, 2, 4, etc, and odd levels are respectively 1, 3, 5, etc. We assume in the next points that the root element is at the first level, i.e., 0. Example of Min-max heap

  4. Binary heap - Wikipedia

    en.wikipedia.org/wiki/Binary_heap

    A binary heap is defined as a binary tree with two additional constraints: [3] Shape property: a binary heap is a complete binary tree; that is, all levels of the tree, except possibly the last one (deepest) are fully filled, and, if the last level of the tree is not complete, the nodes of that level are filled from left to right.

  5. Stern–Brocot tree - Wikipedia

    en.wikipedia.org/wiki/Stern–Brocot_tree

    In number theory, the Stern–Brocot tree is an infinite complete binary tree in which the vertices correspond one-for-one to the positive rational numbers, whose values are ordered from the left to the right as in a search tree. The Stern–Brocot tree was introduced independently by Moritz Stern and Achille Brocot .

  6. Heap (data structure) - Wikipedia

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

    Example of a binary max-heap with node keys being integers between 1 and 100. In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key (the value) of P is greater than or equal to the key of C.

  7. m-ary tree - Wikipedia

    en.wikipedia.org/wiki/M-ary_tree

    A full m-ary tree is an m-ary tree where within each level every node has 0 or m children. A complete m-ary tree [3] [4] (or, less commonly, a perfect m-ary tree [5]) is a full m-ary tree in which all leaf nodes are at the same depth.

  8. Catalan number - Wikipedia

    en.wikipedia.org/wiki/Catalan_number

    It follows that C n is the number of full binary trees with n + 1 leaves, or, equivalently, with a total of n internal nodes: The associahedron of order 4 with the C 4 =14 full binary trees with 5 leaves. C n is the number of non-isomorphic ordered (or plane) trees with n + 1 vertices. [7] See encoding general trees as binary trees.

  9. Tree (abstract data type) - Wikipedia

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

    Search trees store data in a way that makes an efficient search algorithm possible via tree traversal. A binary search tree is a type of binary tree; Representing sorted lists of data; Computer-generated imagery: Space partitioning, including binary space partitioning; Digital compositing; Storing Barnes–Hut trees used to simulate galaxies ...
