分析: 考察BST + 完全二叉树的性质,注意: (1):先用排序排好,然后由于是完全二叉树,我们使用中序来建树. (2):建好之后,层次遍历可以采用队列. #include <iostream> #include <stdio.h> #include <algorithm> #include <cstring> #include <vector> #include <queue> #include <cmath> usi…

因为是要构造完全二叉树,所以树的形状已经确定了. 因此只要递归确定每个节点是多少即可. #include<cstdio> #include<cstring> #include<cmath> #include<queue> #include<vector> #include<string> #include<stack> #include<map> #include<algorithm> using…

由于是满二叉树,用数组既可以表示父节点是i,则左孩子是2*i,右孩子是2*i+1另外根据二分搜索树的性质,中序遍历恰好是从小到大排序因此先中序遍历填充节点对应的值,然后再层次遍历输出即可. 又是一道遍历的水题... #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <queue> using namespace std;…

Complete Binary Search Tree PAT-1064 本次因为涉及到完全二叉排序树,所以可以使用数组的形式来存储二叉排序树 对输入序列排序后,得到的是中序遍历二叉排序树的序列.对这颗二叉排序树进行中序遍历,将每个结点的值放入二叉树的存储数组中,最后遍历数组即可求出层次遍历的序列. 此题需要注意层次遍历和数组存储二叉树的关系,利用这个关系可以快速解题. /** * @Author WaleGarrett * @Date 2020/9/5 8:20 */ import java.…

这题也是第二次做,本想第一次做时参考的算法会和老师讲的一样,不想老师讲的算法用在这题感觉还不如思雪园友的算法(http://www.cnblogs.com/sixue/archive/2015/04.html)来的简单,不过老师给的思路是一种挺通用的思路,可以用来解决一系列的问题,但我目前看着有点吃力.我坚持认为对全局变量的使用需十分谨慎,能不用就不用,所以为了不出现全局变量,就无辜多了一串参数.实现代码如下,题目在代码下方 #include <stdio.h> #include <st…

完全二叉树 刚开始只发现了中序遍历是从小到大顺序的.一直在找完全二叉树的层结点间规律...放弃了 不曾想,完全二叉树的规律早就知道啊.根结点为i,其左孩子结点2*i, 右孩子结点2*i+1. 结合此两者即可解决问题! A Binary Search Tree (BST) is recursively defined as a binary tree which has the following properties: The left subtree of a node contains on…
