照你这样肯定RE
```cpp
for(i=1;;i++){
a*=3,b*=2;
if(a>b)
return printf("%d\n",i);0;
}
```
这样return了是不能退出的，还是老老实实break吧

```cpp
蜜汁原因，应该是你的return printf有点问题
#include<bits/stdc++.h>
using namespace std;
int a,b;
int main()
{
int i;
scanf("%d%d",&a,&b);
for(i=1;;i++)
{
a*=3,b*=2;
if(a>b)
{printf("%d\n",i);return 0;}
}
return 0;
}
```

原谅我蜜汁原因加了个&就AC

其实可以这样。。。
```cpp
return !printf("%d\n",i);
```

应该还可以这样...
```
return printf("%d\n",i),0;
```
