If marks of two student is equal give priority to Roll or Math marks or Biology marks we have to tell it to computer .

include

using namespace std;

public:
string name ;
int roll ;
int marks ;

this->name = name ;
this->roll =roll ;
this->marks = marks ;
}
};

class cmp{

if(l.marks < r.marks)
return true ;
else
return false ;

};
int main()

cin.tie(NULL);
cout.tie(NULL);
priority_queue,cmp> pq;

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

}

while(!pq.empty()){
