题意:输入一个正整数N(<=1000),接着输入N个非负整数(<=2000),输出完全二叉树的层次遍历. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ]; ]; int cnt; int n; void dfs(int x){ if(x>n) return; dfs(x*); tree[x]=a[++cnt]; dfs(x*+); }

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

题意: 输入一个正整数N(<=1000),接下来输入N个点的序号.如果刚才输入的序列是一颗二叉搜索树或它的镜像(中心翻转180°)的先序遍历,那么输出YES并输出它的后序遍历,否则输出NO. trick: for(auto it:post) cout<<it<<((it!=post[n-1])?" ":""); 这样输出会使第0,1数据点格式错误...原因未知 cout<<post[0]; for(int i=1;i<

title: 04-树6 Complete Binary Search Tree(30 分) date: 2017-11-12 14:20:46 tags: - 完全二叉树 - 二叉搜索树 categories: 数据结构 题目链接 题目大意 给出n个节点,构造一棵完全二叉搜索树. 最后按层次遍历输出这棵树. 分析 搜索二叉树的中序遍历是按照由小到大的顺序遍历的. 而完全二叉树,知道树的结点后就可以唯一确定树的结构,因此知道树的结点数后,中序遍历并将结点由小到大给树赋值,就可以构建出树. AC代
