递归先序遍历二叉树的伪代码(示意代码)如下: travel(tree) { if(tree) { print(tree.data) //遍历当前节点 travel(tree.lchild) //对左孩子递归调用 travel(tree.rchild) //对右孩子递归调用 } } 递归遍历二叉树可以参考递归函数的定义与实现部分的内容: 1递归函数 recursive function :输出正整数N各个位上...

Binary Search 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/Da...
The tree is known as a Binary Search Tree or BST. Traversing the tree There are mainlythreetypes of tree traversals. Pre-order traversal In this traversal technique the traversal order is root-left-right i.e. Process data of root node ...
二叉查找树(英语:Binary Search Tree),也称为二叉搜索树、有序二叉树(ordered binary tree)或排序二叉树(sorted binary tree),是指一棵空树或者具有下列性质的二叉树: 若任意节点的左子树不空,则左子树上所有节点的值均小于它的根节点的值; 若任意节点的右子树不空,则右子树上所有节点的值均大于或等于它的根节...
向一个二叉搜索树b中插入一个节点s的算法,过程为: 若b是空树,则将s所指结点作为根节点插入,否则: 若s->data等于b的根节点的数据域之值,则返回,否则: 若s->data小于b的根节点的数据域之值,则把s所指节点插入到左子树中,否则: 把s所指节点插入到右子树中。(新插入节点总是叶子节点) ...

data in a non-linear fashion. After discussing the properties of binary trees, we'll look at a more specific type of binary tree—the binary search tree, or BST. A BST imposes certain rules on how the items of the tree are arranged. These rules provide BSTs with a sub-linear search ...
