原创 UVa536_Tree Recovery
题目：点击打开链接思路：根据先序遍历找到树根，再在中序遍历中找到树根，从而找到左右树结点中序遍历，然后递归构造左右子树。#define _CRT_SECURE_NO_WARNINGS#include#include#include#include#include#include#include#include#includeusing namespace std;s

题目：点击打开链接思路：对于一节点k，其左右节点编号分别为2k,2k+1。然后模拟题意即可。原题输入比较多，但输入X1、X2.....没有用到。#define _CRT_SECURE_NO_WARNINGS#include#include#include#include#include#include#include#include#includeusing names

原创 UVa673_ Parentheses Balance
题目：点击打开链接思路：遇到“（”或者“["就入栈，遇到"）"或“]"就看栈顶元素是否匹配，不匹配就ok=0;然后继续下一组数据。但这样必须判断最后是否为空串，如测试样列（（（） 输出No。#define _CRT_SECURE_NO_WARNINGS#include#include#include#include#include#include#include#i
