简单题. #include<cstdio> #include<cstring> #include<cmath> #include<vector> #include<map> #include<queue> #include<stack> #include<algorithm> using namespace std; struct Node { int left; int right; }s[]; int n;…

就是把输入给的左孩子右孩子互换一下,然后输出层次遍历和中序遍历. #include <iostream> #include <algorithm> #include <cstring> #include <string.h> #include <cstdio> #include <queue> using namespace std; ; bool first=true; struct Node{ int id; int left;…

题意: 输入一个正整数N(<=10),接着输入0~N-1每个结点的左右儿子结点,输出这颗二叉树的反转的层次遍历和中序遍历. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ][]; ]; void bfs(int r){ queue<int>q; q.push(r); cout<<r; while(!q.empty()){ in…

二叉树有N个结点,给出每个结点的左右孩子结点的编号,把二叉树反转(左右孩子交换  所以是后序遍历交换) 输出反转后二叉树的层序遍历和中序遍历 #include<bits/stdc++.h> using namespace std; ; struct node { int L,R; }s[N]; int toint(char ch) { if(ch=='-'){ ; } else{ '; } } int isroot[N]; void postorder(int root) { ){ retur…
