二叉搜索树(Binary Search Tree,BST): 一种特殊的二叉树,满足以下性质:对于树中的每个节点,其左子树中的值都小于该节点的值,而其右子树中的值都大于该节点的值。BST通常用于实现有序数据集合。 完全二叉树(Complete Binary Tree): 一个二叉树,其所有层次(深度)除了最后一层外,都是完全填充的,且最后一层的节...
我们知道,二叉树的类型被我们定义为BinTree,而它的原类型是指向二叉树结点TNode的指针。我一开始犯的错误是,我认为直接传入这里的指针BinTree给函数CreateBinaryTree()就可以得到创建的二叉树。事实上这里需要传入指针的指针,即这个结构体指针的地址*BinTree。 也就是说,我们事实上传入的是** TNode,即结点指针的指...

二叉搜索树(Binary Search Tree)--C语言描述(转) 图解二叉搜索树概念 二叉树呢,其实就是链表的一个二维形式,而二叉搜索树,就是一种特殊的二叉树,这种二叉树有个特点:对任意节点而言,左孩子(当然了,存在的话)的值总是小于本身,而右孩子(存在的话)的值总是大于本身。
1151 LCA in a Binary Tree C++版 1.题意 给出中序和先序遍历序列,让你找出给定的查询记录的最小父节点,如果给定的值不存在,则按照相应的格式输出。指定的格式如下: For each given pair of U and V, print in a line LCA of U and V is A. if the LCA is found and A is the key. But if...

As we'll see, binary trees store 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 ...
