using namespace std;

int main()
{
    int T;
    cin >> T;
    while(T--)
    {
        int N;
        cin >> N;
        double d,Max = -1;
        while(N--)
        {
            cin >> d;
            if(d > Max)
                Max = d;
        }
        printf("%.2lf\n",Max);
    }

    return 0;
