A binary tree is a finite set of vertices that is either empty or consists of a root r and two disjoint binary trees called the left and right subtrees. There are three most important ways in which the vertices of a binary tree can be systematically traversed or ordered. They are preord...

Binary Tree Traversals 二叉树遍历 In a postorder traversal of the vertices of T, we visit the vertices of T1 in postorder, then the vertices of T2 in postorder and finally we visit r. Now you are given the preorder sequence and inorder sequence of a certain binary tree. Try to find ou...

1710 Binary Tree Traversals 题解 由题意得: 1.输入二叉树的前序遍历和中序遍历,输出这个二叉树的后序遍历 2.前序遍历的顺序是:根-左子树-右子树 中序遍历的顺序是:左子树-根-右子树 后序遍历的顺序是:左子树-右子树-根 3.根据前后遍历找到根后(由定义得:前序遍历的第一个为主根),可以将二叉树分为...
HDU 1710 Binary Tree Traversals(二叉树) 题目地址:HDU 1710 已知二叉树先序和中序求后序。 #include <stdio.h> #include <string.h> int a[1001], cnt; typedef struct node { int date ; node *lchild , *rchild ; }*tree; int getk(int ch,int ino[],int is,int n)...
PAT A1086 Tree Traversals Again 题目 思路 push 为先序遍历 根据题目第一句话 pop为中序遍历 即知道先序遍历和中序遍历来求得后序遍历的顺序 根据先+中= 构建树 根据树后序遍历 在主函数中针对不同的字符串输入需要利用栈分别存在2个数组里。 code... ...

A simple game Γ is given in binary tree form (BF) by a binary tree representing the set Wm(Γ). We use the notation B(Γ) to denote a simple game Γ given in binary tree form. Observe that we can check in polynomial time whether a set belongs or not to the set represented by ...
