95分，10号测试点TLE.咋改？
```cpp
#include<cstdio>
using namespace std;
int main() {
char ch;
bool flag=1;
while((ch=getchar())&&flag)
if(ch=='\\')
if((ch=getchar())=='n') printf("linux"),flag=0;
else if((ch=getchar())=='\\') if((ch=getchar())=='n') printf("windows"),flag=0;
else printf("mac"),flag=0;
return 0;
}
```
