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…

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) { for(int i = is ; i <= is + n -1 ; i++) if(ino[…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1710 题意:给前序.中序求后序,多组 前序:根左右 中序:左右根 分析:因为前序(根左右)最先出现的总是根结点,所以令root为前序中当前的根结点下标(并且同时把一棵树分为左子树和右子树).start为当前需要打印的子树在中序中的最左边的下标,end为当前需要打印的子树在中序中最右边的下标.递归打印这棵树的后序,递归出口为start > end.i为root所表示的值在中序中的下标,所以i即是分隔中…
