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

平衡二叉查找树 Balanced Binary Search Tree 平衡二叉查找树为改进的二叉查找树,其设计原则能够保证在最坏的情况下,其插入、删除和查找操作也可以实现渐进运行时间为 O(log n) 。 平衡二叉查找树,可以理解为是一种不太严格的平衡树。常见的平衡二叉搜索树有 AVL 树(Adelson-Velsky and Landis Tree)、红黑树(Red...
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 abstraction state and several other transactions that ...
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. ...
