Both the left and right subtrees must also be binary search trees. A Complete Binary Tree (CBT) is a tree that is completely filled, with the possible exception of the bottom level, which is filled from left to right. Now given a sequence of distinct non-negative integer keys, a unique...
The right subtree of a node contains only nodes with keys greater than or equal to the node's key. Both the left and right subtrees must also be binary search trees. A Complete Binary Tree (CBT) is a tree that is completely filled, with the possible exception of the bottom level, whi...
intn,number[maxn],CBT[maxn]; intindex=0;//index如果在string.h头文件下会报错重定义(要改名) //或者将string.h头文件直接改成string头文件 voidinOrder(introot){//中序遍历 if(root>n)return;//空结点,直接返回 inOrder(root*2);//往左子树递归 CBT[root]=number[index++];//根结点处赋值numbe...
那么,我们结合完全二叉树的数组形式和中序遍历,可以获得首个所访问节点的下标index,将树节点Node的有序数组的首个节点Trees[0]赋给这个下标对应的某个数组空间——假定它是Level,就实现了在中序遍历中将Trees映射到对应的Level从而可知层序遍历的顺序。 #include <iostream> #include <stdio.h> #include <vector>...

PAT甲级1064 Complete Binary Search Tree(JAVA版) 本题考查 二叉搜索树、完全二叉树 解题思路 一个重要的规则:二叉搜索树的中序遍历满足结点权值从小到大排列 完全二叉树最底层结点由左向右排列 首先有现有结点数计算根结点索引,然后对左子树递归该方法,对右子树递归该方法。 根节点索引根据左右子树结点个数来确定...
1064 Complete Binary Search Tree (30分) 题目A Binary Search Tree (BST) is recursively defined as a binary tree which has the following properties: The left subtree of a node contains only nodes with keys less than the node’s key. The r......
原题链接:1064 Complete Binary Search Tree (30 分) 题目大意: 完全二叉树 (CBT) 定义为除最深层外的其他层的结点数都达到最大个数,最深层的所有结点都连续集中在最左边的二叉树。 现在,给定 N 个不同非负整数,表示 N 个结点的权值,用这 N 个结点可以构成唯一的完全二叉搜索树。不知道什么是二叉搜索树(...
