解法: 1.先将对应的字符串存入map. 2.然后将输入的串的second置为空. 3.输出6-n,输出map中的非空串. 代码: #include <bits/stdc++.h> using namespace std; typedef long long ll; map <string,string> m; int main(){ m["purple"] = "Power"; m["green"] = "Ti…

这次的题目难得的水,但是由于许多哲学的原因,第二题题意表述很迷. 然后是真的猜题意了搞了. 不过这样都可以涨Rating我也是服了. Upt:链接莫名又消失了 A. 「NOIP2017模拟赛11.03」Egypt丶小黑车 题意一看就是很精简的数学题, 首先我们用经典的方法,假设我们用\(f_x\)表示\([1,x]\)的答案,那么最后输出的就是\(f_r-f_{l-1}\)了 然后考虑求解\(f_x\).我们知道对于一个\([1,x]\)的区间里,含有约数\(d\)的数有\(\lfloor \f…

今天回来打的第一场NOIP难度的试题,结果惨不忍睹.写一下每道题的做法,然后每道题犯的__弱智__错误 UPD:2018.9.15 突然这篇题解就变成很多大佬要看的了,因为之前是写给自己看的,所以写的很简略,这次修改一下第二道题的描述(第一题建议找其他AC的人看看,我的做法比较依赖STL,而且比较难读懂) Moni 题意 每天 \(t\) 时刻将会有人取车或者放车,这个序列满足FIFO原则,每个人的时间代价是 \(delta(t)\). 有 \(q\) 次询问,每次问你如果在初始时刻投放 \(c…

为了方便app开发过程中,不受服务器接口的限制,便于客户端功能的快速测试,可以在客户端实现一个模拟服务器数据接口的MockApi模块.本篇文章就尝试为使用gradle的android项目设计实现MockApi. 需求概述 在app开发过程中,在和服务器人员协作时,一般会第一时间确定数据接口的请求参数和返回数据格式,然后服务器人员会尽快提供给客户端可调试的假数据接口.不过有时候就算是假数据接口也来不及提供,或者是接口数据格式来回变动--很可能是客户端展示的原因,这个是产品设计决定的,总之带来的问题…
