cin, cout을 하면 시간 초과가 되므로 printf, scanf를 사용.

float 형으로 변수를 받아와서 처리하면 된다.

#include <iostream>
#include <cstdio>

using namespace std;

int main(void)
{
    ios::sync_with_stdio(false);
    cin.tie(0);
    cout.tie(0);
    
    int t;
    //cin >> t;
    scanf("%d", &t);
    
    for(int tc = 1; tc <= t; tc++)
    {
        float a, b, c, d;
        float r1, r2;
        
        //cin >> a >> b >> c >> d;
        scanf("%f %f %f %f", &a, &b, &c, &d);
        r1 = float(a / b);
        r2 = float(c / d);
        
        if(r1 > r2)
            //cout << "#" << tc << " " << "ALICE" << endl;
            printf("#%d ALICE\n", tc);
        else if(r1 < r2)
            //cout << "#" << tc << " " << "BOB" << endl;
            printf("#%d BOB\n", tc);
        else
            //cout << "#" << tc << " " << "DRAW" << endl;
            printf("#%d DRAW\n", tc);
    }
    return 0;
}
