#include <iostream>

using namespace std;

int main()
{
    long long int A,B,C;
    int T;//测试用例的个数
    cin >> T;
    for (int i = 0; i < T; i++)
    {
        cin >> A >> B >> C;
        if ( A + B > C ) cout << "Case #" << i+1 << ":" << " true" << endl;
        else cout << "Case #" << i+1 << ":" << " false" << endl;
    }
    return 0;
}

要用Long Long int
