using namespace std;

int N;

cin >> N;

int a, b, c;

while(cin >> a >> b >> c){

if(a == 1){

cout << b + c << endl;

}else if(a == 2){

cout << b - c << endl;

}else if(a == 3){

cout << b * c << endl;

}else{

if(b < c){

cout <<  0 << endl;

}else{

cout << b/c << endl;

}

}

}

}

請注意題目範圍

1 <= b , c <= 2147483647

翻譯一下就是 b*c 會超過 int 的範圍，請換成 long 或 long long
