比较简单的一题 遍历左右的时候注意一下 #include<bits/stdc++.h> using namespace std; ; ]; ; vector<int>t; vector<int>p[N]; int n; void dfs(int v) { ){ ; ]!=-||s[i*+]!=-){ return; } p[cnt++]=t; return ; } t.push_back(s[v]); dfs(v*+); dfs(v*); t.pop_back(); }…

题意分析: 给出一个1000以内的整数N,以及N个整数,并且这N个数是按照完全二叉树的层序遍历输出的序列,输出所有的整条的先序遍历的序列(根 右 左),以及判断整棵树是否是符合堆排序的规则(判断是大顶堆,小顶堆,不是堆) 题解分析: 由于给出的整数序列是按照完全二叉树的层序遍历,所以不存在中间有空的节点,并且层序遍历满足1~N的节点顺序正好方便我们一边输入一边建立完全二叉树,之后就是正常的先序遍历(这题要求根 右 左),有所区别的是最后的输出每次到达最后一个叶子节点的时候都需要输出一遍整条序列,…
