开个新号打打codeforces(以前那号玩废了),结果就遇到了这么难一套.touristD题用了map,被卡掉了(其实是对cf的评测机过分自信),G题没过, 700多行代码,码力惊人.关键是这次tourist掉到第二了,掉了200多分,为神节哀. 做了4道,要不是第4题一直炸第5题也能做出来.本来想着上蓝名的.然后我第二题挂了,判断循环节写错了.绝望啊---- 比赛传送门:http://codeforces.com/contest/1043 A. Elections 这题很简单,就是说有n个人…

A题: 题目地址:Currency System in Geraldion 题意:给出n中货币的面值(每种货币有无数张),要求不能表示出的货币的最小值.若全部面值的都能表示,输出-1. 思路:水题,就是看看有没有面值为1的货币,假设有的话,全部面值的货币都能够通过1的累加得到,假设没有的话.最小的不能表示的就当然是1辣. #include <stdio.h> #include <math.h> #include <string.h> #include <stdli…

A. Currency System in Geraldion: 题意:有n中不同面额的纸币,问用这些纸币所不能加和到的值的最小值. 思路:显然假设这些纸币的最小钱为1的话,它就能够组成随意面额. 假设这些纸币的最小值大于1,那么它所不能组成的最小面额就是1.所以自学求最小值就可以. 我的代码: #include <set> #include <map> #include <cmath> #include <stack> #include <queue…
