problem in formate of submission, what the wrong with this source code.

#include
#include
using namespace std;

int main()
{
int t; // no. of test cases
cin>>t;

while(t--){
int n; //inputs

float t1,v1,v2,t2;
cin>>n>>v1>>v2;
t1= (sqrt(2)*n)/v1;

t2=(2*n)/v2;

if(t1>t2){
	
	cout<<"stairs"<<endl;
}
else
{ 
   cout<<"elevator"<<endl;
}
}

return 0;
}

You have to print the way which is quicker. Your conditions seem opposite of what they are supposed to be :confused:
