  2. Binary tree - Wikipedia

    en.wikipedia.org/wiki/Binary_tree

    A full binary tree An ancestry chart which can be mapped to a perfect 4-level binary tree. A full binary tree (sometimes referred to as a proper, [15] plane, or strict binary tree) [16] [17] is a tree in which every node has either 0 or 2 children.

  3. 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 ...

  4. Left-child right-sibling binary tree - Wikipedia

    en.wikipedia.org/wiki/Left-child_right-sibling...

    6-ary tree represented as a binary tree. Every multi-way or k-ary tree structure studied in computer science admits a representation as a binary tree, which goes by various names including child-sibling representation, [1] left-child, right-sibling binary tree, [2] doubly chained tree or filial-heir chain.

  5. Succinct data structure - Wikipedia

    en.wikipedia.org/wiki/Succinct_data_structure

    Another example is the representation of a binary tree: an arbitrary binary tree on nodes can be represented in + bits while supporting a variety of operations on any node, which includes finding its parent, its left and right child, and returning the size of its subtree, each in constant time.

  6. Binary search tree - Wikipedia

    en.wikipedia.org/wiki/Binary_search_tree

    Fig. 1: A binary search tree of size 9 and depth 3, with 8 at the root. In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in its right subtree.

  7. Implicit data structure - Wikipedia

    en.wikipedia.org/wiki/Implicit_data_structure

    Such a tree occurs notably for an ancestry chart to a given depth, and the implicit representation is known as an Ahnentafel (ancestor table). This can be generalized to a complete binary tree (where the last level may be incomplete), which yields the best-known example of an implicit data structure, namely the binary heap , which is an ...

  8. 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.

  9. Range query tree - Wikipedia

    en.wikipedia.org/wiki/Range_query_tree

    A Range Query Tree is a complete binary tree that has a static structure, meaning that its content can be changed but not its size. The values of the underlying array over which the associative operation needs to be performed are stored in the leaves of the tree and the number of values have to be padded to the next power of two with the identity value for the associative operation used.
