思路: 构造题.首先把字符串变成“(((((...)))))”的样子,再根据k的取值变成“()()()...((...))”的样子即可. 实现: #include <bits/stdc++.h> using namespace std; int main() { int T; cin >> T; while (T--) { int n, k; string s; cin >> n >> k >> s; vector<pair<int,…

题目链接:http://uoj.ac/problem/239 题目大意: 这是一道交互题,交互库维护了一个数据结构,可以存储n为二进制串,一开始你可以向空的数据结构中插入若干二进制串, 接下来这个数据结构会将其中存储的二进制串进行改变. 改变的方法是生成一个0到n-1的排列pi,将原来的二进制串a0a1a2..an-1变成ap0ap1..apn-1. 接着你可以进行询问,每次询问一个串是否在这个数据结构当中,要求你在不超过w次插入和r次询问中求出排列p 分析:读完题后看看数据范围,w=r=896…

Case:同样的代码,本地开发环境(local is Chinese Simplify)可以成功运行,但是放到Windows Server 2008 R2(Local is United State) 上,同样的代码失败了.最后跑到server上用vs2012 获取最新代码发现所有的中文都是乱码. Solution1:只该代码,其它设置不变(server 上的是设置不是我们这些小兵想动就可以动的).我写了两个方法. public bool CompareChineseString(string…
