Implementation

P_1_Squirrnect_4.cpp

C++

    #include <bits/stdc++.h>
    using namespace std;
    using ll = long long;
    using i128 = __int128;
    const int inf = 1e9;
    const ll INF = 2e18; //❄️
    int main() {
        ios::sync_with_stdio(0); cin.tie(0); 
        int t; cin >> t;
        for (int i = 0; i < t; i++) {
            int x, y; cin >> x >> y;
            if (x == 1 || (y == 1 && x < 7)) cout << "bad" << '\n';
            else cout << (x >= 4 || y >= 4 ? "good" : "bad") << '\n';
        }
        return 0;
    }
