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   Recommend

大数除法取余，模拟除法过程

#include <stdio.h> #include <string.h> using namespace std; int main() { int i; char ch[10000005]; int mod, cnt = 1; while ( ~scanf ( "%s", ch ) ) { int len = strlen(ch); mod = 0; for ( i = 0; i < len; i++ ) { mod = (mod*10+ch[i]-'0')%10001; } if ( mod ) { printf ( "Case #%d: NO\n", cnt ); } else { printf ( "Case #%d: YES\n", cnt ); } cnt++; } }
