最后一个样例错了

建议在第一个 ```if``` 中加入$return 0$

```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,c,sum,a1,b1,c1;
cin>>a>>b>>c;
sum=a+b+c;
a1=min(a,min(b,c));
c1=max(a,max(b,c));
b1=sum-a1-c1;
if(a1+b1<=c1){
cout<<"Not triangle";
return 0;
}
if(a1*a1+b1*b1==c1*c1)
cout<<"Right triangle"<<endl;
if(a1*a1+b1*b1>c1*c1)
cout<<"Acute triangle"<<endl;
if(a1*a1+b1*b1<c1*c1)
cout<<"Obtuse triangle"<<endl;
if(a==b||a==c||b==c)
cout<<"Isosceles triangle"<<endl;
if(a==b&&a==c&&b==c)
cout<<"Equilateral triangle"<<endl;
return 0;
}
```
