a>=2*b要用long long,亲们!因为2*b可能超过int的范围,附AC代码#include <stdio.h>
int main()
{
int a,b,t;
while(scanf("%d%d",&a,&b)!=EOF)
{
if(a+b==0)break;
if(a<b)
a=a^b,b=a^b,a=a^b;
t=0;
while(a%b!=0)
{
if(a/b>=2)break;
a=a-b;
if(a<b)
a=a^b,b=a^b,a=a^b;
t=!t;
}
if(!t)
printf("Stan wins\n");
else
printf("Ollie wins\n");
}
return 0;
}
