using namespace std;

class car{

public:

    string car_name;

    int x,y;

    

    car(){

        

    }

    

    car(string n , int x , int y){

        car_name = n;

        this->x = x;

        this->y = y;

    }

    

    int dist(){

        // returns square of distance from origin

        return (x*x + y*y);

    }

};

bool compare(car a , car b){

int da = a.dist();

int db = b.dist();



int dla = a.length();  // its giving error here 

int dlb = b.length();



if(da == db){

    return dla < dlb;

}



da<db;

}

int main()

{

int n;

std::cin >> n;

vector<car> v;



for (int i = 0; i < n; i++) {

    int x,y;

    string name;

    cin>>name>>x>>y;

    car temp(name,x,y);

    v.push_back(temp);

    

}



sort(v.begin() , v.end() , compare);



for(auto c : v){

    cout<<"Car "<<c.car_name<<"Distance"<<c.dist()<<"Location"<<c.x<<","<<c.y<<endl;

}



return 0;

}
