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[…

传送门 Description 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…

acm.hdu.edu.cn/showproblem.php?pid=1710 [题意] 给定一棵二叉树的前序遍历和中序遍历,输出后序遍历 [思路] 根据前序遍历和中序遍历递归建树,再后续遍历输出 malloc申请空间在堆,函数返回,内存不释放,需要free手动释放 [Accepted] #include<iostream> #include<cstdio> #include<string> #include<cstring> #include<alg…

题意:给出一颗二叉树的前序遍历和中序遍历,输出其后续遍历 首先知道中序遍历是左子树根右子树递归遍历的,所以只要找到根节点,就能够拆分出左右子树 前序遍历是按照根左子树右子树递归遍历的,那么可以找出这颗树的根节点, 然后拆分出左右子树,对左右子树进行相同的操作,也就是将建树的这个函数递归调用下去 build函数还是理解了好久啊话说= =仍然是学习的代码 #include<iostream> #include<cstdio> #include<cstring> #inclu…
