第一个测试点的输出应该没什么问题但就是wa掉了QAQ

#include <bits/stdc++.h>

using namespace std;

int main() { int a[2]; for(int i=0;i<3;i++) { cin>>a[i];

}
sort(a,a+3);

if(a[0]+a[1]<=a[2]) cout<<"Not triangle"<<endl;

else 
{
	if((a[0]*a[0]+a[1]*a[1])>(a[2]*a[2])) cout<<"Acute triangle"<<endl;
	if((a[0]*a[0]+a[1]*a[1])==(a[2]*a[2])) cout<<"Right triangle"<<endl;
	if((a[0]*a[0]+a[1]*a[1])<(a[2]*a[2])) cout<<"Obtuse triangle"<<endl;


    if(a[0]==a[1]||a[1]==a[2]) cout<<"Isosceles triangle"<<endl;
	if(a[0]==a[2]) cout<<"Equilateral triangle"<<endl;
};


return 0;

}
