题目见这里 分析:分四步进行 1)根据给定的结点情况建二叉树  2)对输入的键值排序(asending) 3)对二叉树中序遍历,同时对应赋key值 4)层次遍历(队列应用) 题目并不困难,但是我误入了trick,错误假定了结点按先序遍历是按顺序编号的(当然是受样例的影响),所以有了下面22分(满分30)   的submit(贴出来是因为这不失为好的巩固二叉树知识的程序) #include <stdio.h> #include <stdlib.h> //qsort,malloc #d…

预处理每个节点左子树有多少个点. 然后确定值得时候递归下去就可以了. #include<cstdio> #include<cstring> #include<cmath> #include<vector> #include<map> #include<queue> #include<stack> #include<algorithm> using namespace std; struct Node { int…

题目就是给出一棵二叉搜索树,已知根节点为0,并且给出一个序列要插入到这课二叉树中,求这棵二叉树层次遍历后的序列. 用结构体建立节点,val表示该节点存储的值,left指向左孩子,right指向右孩子.中序遍历的顺序正好是序列从小到大的顺序,因此中序遍历的时候顺便赋值就可以了,最后层次遍历输出. 思路一:中序遍历的时候赋值 #include <iostream> #include <cstdio> #include <algorithm> #include <str…

题意: 输入一个正整数N(<=100),接着输入N行每行包括0~N-1结点的左右子结点,接着输入一行N个数表示数的结点值.输出这颗二叉排序树的层次遍历. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; pair<]; ]; ; ]; void dfs(int x){ ) return ; dfs(a[x].first); ans[x]=b[++c…

Build A Binary Search Tree PAT-1099 本题有意思的一个点就是:题目已经给出了一颗排序二叉树的结构,需要根据这个结构和中序遍历序列重构一棵二叉排序树. 解法:可以根据中序遍历的思路,首先将给定的序列串进行排序即是中序遍历的结果.接着,根据给定的树结构进行中序遍历,这期间就可以确定每个结点的值.最后,只需要根据这棵树就能进行层次遍历了. 题目具备一些难度,需要一些思维能力和扩展能力. import java.util.ArrayList; import java.u…
