[LeetCode] 173. Binary Search Tree Iterator Java 题目: Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST. Calling next() will return the next sma
Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST. Calling next() will return the next smallest number in the BST. Note: next() and hasNext() should run in average O(1) time and uses O(h) memory, where h is the...

我理解的数据结构(五)—— 二分搜索树(Binary Search Tree) 一、二叉树 和链表一样,动态数据结构 具有唯一根节点 每个节点最多有两个子节点 每个节点最多有一个父节点 具有天然的递归结构 每个节点的左子树也是二叉树 每个节点的右子树也是二叉树 一个节点或者空也是二叉树 ...
java 代码实现binary search tree 如何用Java实现二叉搜索树 在开始实现二叉搜索树(Binary Search Tree,简称BST)之前,我们首先要明确它的基本概念和操作。二叉搜索树是一种特殊的二叉树,具有以下特性: 每个节点都包含一个键值。 节点的左子树中所有节点的键值均小于该节点的键值。

Deletion Operation There are three cases for deleting a node from a binary search tree. Case I In the first case, the node to be deleted is the leaf node. In such a case, simply delete the node from the tree. 4 is to be deleted ...
