There is  73  days in Xixi a year and  137  days in Haha a year.  Now you know the days  N  after Big Bang, you need to answer whether it is the first day in a year about the two planets.   Input There are several test cases(about  5  huge test cases). For each test, we have a line with an only integer  N(0≤N) , the length of  N  is up to  10000000 .   Output For the i-th test case, output Case #i: , then output "YES" or "NO" for the answer.   Sample Input 10001 0 333   Sample Output Case #1: YES Case #2: YES Case #3: NO   Author UESTC   Source 2016中国大学生程序设计竞赛 - 网络选拔赛 题意：有两个周期，求n%两个数是不是相等，相等输出YES，否则NO

思路：虽然本人是蒟蒻，不过此题抢到了一血还是挺开心的= = 

后面惨不忍睹了。最后A了四个题学校水平不行也晋级不了，可惜。

只要对每一位都取模即可，具体可以看代码。

代码：

#include <iostream> #include <cstdio> #include <cstring> #include <algorithm> #include <cmath> using namespace std; #define N 10000050 char a[N]; int main() { int n=1; while(~scanf("%s",&a)) { int len=strlen(a); int now=0,now1=0; for(int i=0;i<len;i++) { now=(now*10+a[i]-'0')%73; now1=(now1*10+a[i]-'0')%137; } if(now==now1) printf("Case #%d: YES\n",n++); else printf("Case #%d: NO\n",n++); } return 0; }
