// 查找节点的方法booleansearch(intkey){returnsearchRec(root,key);// 从根节点开始递归查找}// 递归查找的辅助函数booleansearchRec(Noderoot,intkey){// 基本情况:如果当前节点为空,返回falseif(root==null){returnfalse;}// 如果找到了关键字,返回trueif(key==root.key){returntrue;}// 根据BST特性继续...
二、完整代码实现(Java) 1、二叉搜索树 1.1、 基本概念 二叉树的一个性质是一棵平均二叉树的深度要比节点个数N小得多。分析表明其平均深度为O(N)O(N),而对于特殊类型的二叉树,即二叉查找树(binary search tree),其深度的平均值为O(logN)O(logN)。 二叉查找树的性质: 对于树中的每个节点X,它的左子树中...

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 ...
In this case, the order of the nodes will be: 6 4 8 3 5 7 9 5. Conclusion In this article, we learned how to implement a sorted binary tree in Java, and its most common operations. The full source code for the examples is availableover on GitHub....
