[题目] distinct 不同的 postorder 后序的 inorder 中序的 sequence 顺序:次序:系列 traversal 遍历 题目大意:给出二叉树的后序遍历和中序遍历,求层次遍历. [思路] 参见<算法笔记> [AC代码] #include<iostream> #include<queue> using namespace std; #define N 32 struct node { int data; node *lchild, *rchil…

这是一题二叉树遍历的典型题,告诉我们中序遍历和另外一种遍历序列,然后求任何一种遍历序列. 这题的核心: 建树 BFS #include<bits/stdc++.h> using namespace std; const int MAXN=35; int post[MAXN]; int in[MAXN]; int pre[MAXN]; int n; struct node{ int data; node* lchild; node* rchild; }; node* create(int pos…

Tree Traversals 原题链接 常见的二叉树遍历的题目,根据后序遍历和中序遍历求层次遍历. 通过后序遍历和中序遍历建立起一棵二叉树,然后层序遍历一下,主要难点在于树的建立,通过中序遍历和后序遍历的特点递归求解,详细内容见代码 #include <iostream> #include <queue> using namespace std; struct TreeNode{ int val; TreeNode* left; TreeNode* right; }; ]; ];…
