using namespace std;


int main()
{

            return s;

        }
        public static void Main()

        {
            int T = Convert.ToInt32(Console.ReadLine());
            for (int i = 0; i < T;i++ )
            {
                int n = Convert.ToInt32(Console.ReadLine());

                Console.WriteLine(Sqrt(n));
