【题目意思】给你一个数，问你它是不是137和73的倍数。

【题目分析】137和73的最小公倍数是10001，然后问题就转化为问这个数是不是10001的倍数，接下来就简单了。

下面是AC代码：

#include<cstdio>
#include<cstring>
#include<algorithm>
using namespace std;

char a[10000005];
int main()
{
int kase=0;
while(~scanf("%s",a))
{
int sum=0;
for(int i=0;a[i]!='\0';i++)
{
sum=(sum*10+a[i]-'0')%10001;
}
if(sum==0)
{
printf("Case #%d: YES\n",++kase);
}
else
{
printf("Case #%d: NO\n",++kase);
}
}
return 0;
}
