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 解题报告：大数问题，套模板就行。记住不要用cin； code： #include<iostream> #include<algorithm> #include<stdio.h> #include<queue> #include<math.h> #include<string.h> #include<stdlib.h> using namespace std; typedef long long ll; const int N=10000005; char s[N]; int main(){ // freopen("input.txt","r",stdin); int k=1; int n=10001; while(~scanf("%s",s)){ int len=strlen(s); if(s[0]=='0') printf("Case #%d: YES\n",k++); else{ int mod=0; for(int i=0; i<len; i++) { mod=mod*10+s[i]-'0'; mod=mod%n; } if(mod==0) printf("Case #%d: YES\n",k++); else printf("Case #%d: NO\n",k++); } } return 0; }
