1064. Complete Binary Search Tree 题目大意 给定一个序列, 求其 生成Complete BST 的层序遍历. 思路 最开始把这个题想复杂了, 还想着建立结构体, 其实用数组最为方便简单 中序遍历这棵 Complete BST, 依次填入一个排好序的序列. 因为是数组存放, 所以直接输出 1 - nNode 就好. 代码 #include <iostream> #include <cstdio> #include <vector> #in…

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…
