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,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...
二叉树(Binary Tree)是一种树形数据结构,由节点构成,每个节点最多有两个子节点:一个左子节点和一个右子节点。 publicclassTreeNode{intval; TreeNode left; TreeNode right; TreeNode(intval) {this.val = val; } } 基本概念 "二叉树"(Binary Tree)这个名称的由来是因为二叉树的每个节点最多有两个子节点...

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 A is one of U and V, print X is an ancestor of Y. where X is A and Y is the other node. If U or V is not found in the binary tree, print in...
In Computer Science, a binary tree is a hierarchical structure of nodes, each node referencing at most to two child nodes. Every binary tree has a root from which the first two child nodes originate. If a node has no children, then such nodes are usually termed leaves, and mark the exte...

1. Write the definition of the function, nodeCount, that returns the number of nodes in the binary tree. Add this function to the class binaryTreeType and create a program to test this function. 2. Write the definition of the function, leavesCount, that takes as a parameter a pointer to...
