Description 题目描述 It's Saturday today, what day is it after 11 + 22 + 33 + ... + NN days? 今天是星期六,11 + 22 + 33 + ... + NN 天后是星期几? Input 输入 There are multiple test cases. The first line of input contains an integer T indicating the number of test cases.…

题目 思路:比赛的时候有想过找循环节,但是,打表打错了. 后来,看着过了挺多人,就急了, 看了一下别人的时间 耗时都挺长的,就以为不是找规律, 没想到真是找规律,不过,这个题的数据可能挺大的. AC代码: #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> using namespace std; ][] = {"Saturday",…

原题: ZOJ 3785 http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemCode=3785 题意:当天是星期六,问经过1^1+2^2+3^3....+n^n天后是星期几? 这题开始以为是这种式子的求和问题,翻了半天没翻到公式.结果没搞出来.后来发现有两种方法. 第一种方法: 找规律 打表可以看出,这些数的结果出现42一循环,所以直接就处理出前42个,后面的就用前面的. 代码: #include <iostream> #inclu…
