5. 二叉搜索树不仅支持搜索操作,还支持查找最小值、最大值、后继节点( successor )、前驱节点( predecessor ) 搜索,通过递归能轻易实现搜索操作. TREE-SEARCH(X)ifx == NIL or k ==x.key return xifk <x.key return TREE-SEARCH(x.left)elsereturn TREE-SEARCH(x.right) 迭代版代码如下 ITERATIVE-TREE-...

二叉查找树(Binary Search Sort)又称二叉查找树(Binary Search Tree),亦称二叉搜索树,缩写为BST。BST是一种数据结构,支持多种动态集合操作,包括SEARCH、MINIMUM、MAXIMUM、INSERT、DELETE等,既可以用作字典,也可以用作优先队列。 代码实现请见:https://github.com/xixy/algorithms/blob/master/DataStructure/bst.py ...
In computer science, a binary search tree (BST), sometimes also called an ordered or sorted binary tree, is a node-based binary tree data structure which has the following properties: The left subtree of a node contains only nodes with keys less than the node's key. ...

We propose a binary search tree data structure whose key novelty stems from the decoupling of update operations, ie, instead of performing an update operation in a single large transaction, it is split into one transaction that modifies the ion state and several other transactions that restructure...
**Note **Realize that AVL trees are binary search trees, so in addition to maintaining a balance property, an AVL tree must also maintain the binary search tree property. When creating an AVL tree data structure, the challenge is to ensure that the AVL balance remains regardless of the oper...

Class Library—binary trees. Whereas arrays arrange data linearly, binary trees can be envisioned as storing data in two dimensions. A special kind of binary tree, called a binary search tree, or BST, allows for a much more optimized search time than with unsorted arrays. (30 printed pages)...
