  1. Search tree

    In computer science, a search tree is a tree data structure used for locating specific keys from within a set. In order for a tree to function as a search tree, the key for each node must be greater than any keys in subtrees on the left, and less than any keys in subtrees on the right.The advantage of search trees is their efficient search time given the tree is reasonably balanced, which is to say the leaves at either end are of comparable depths. Various search-tree data structures exist, several of which also allow efficient insertion and deletion of elements, which operations then have to maintain tree balance. Search trees are often used to implement an associative array. The search tree algorithm uses the key from the key–value pair to find a location, and then the application stores the entire key–value pair at that particular location.

  1. Search tree

    In computer science, a search tree is a binary tree data structure in whose nodes data values are stored from some ordered set, in such a way that in-order traversal of the tree visits the nodes in ascending order of the stored values. This means that for any internal node containing a value v, the values x stored in its left subtree satisfy x ≤ v, and the values y stored in its right subtree satisfy v ≤ y. Each subtree of a search tree is by itself again a search tree. Search trees can implement the data type of multisets. The advantage of using search trees is that the test for membership can be performed efficiently provided that the tree is reasonably balanced, that is, the leaves of the tree are at comparable depths. Various search-tree data structures exist, several of which also allow efficient insertion and deletion of elements, which operations then have to maintain tree balance. If the multiset being represented is immutable, this is not an issue. Search trees can also implement associative arrays by storing key–value pairs, where the ordering is based on the key part of these pairs. In some kinds of search trees the data values are all stored in the leaves of the tree. In that case some additional information needs to be stored in the internal tree nodes to make efficient operations possible.
