I successfuly passed it on Pascal... But i can't do it in C#...  3 Test WA!!!! I used "en-US" format (for example 5.0432). If someone did it please tell what can be wrong....
using System;
using System.Text;
using System.IO;
using System.Threading;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            System.Globalization.CultureInfo local = new System.Globalization.CultureInfo("en-US");
            long count = -1;
            long[] In = new long[1000000];
            int ChrSt;
            string StrIn;
            string StrSt = "";
            while ((ChrSt=Console.In.Read())>0)
            {
                if ((ChrSt >= '0') && (ChrSt <= '9'))
                    StrSt += (char)ChrSt;
                else
                {
                    if (StrSt != "")
                    {
                        count++;
                        long.TryParse(StrSt, out In[count]);
                        StrSt = "";
                    }
                }
            }

            for (long i = count; i > -1; i--)
            {

                Console.WriteLine(Math.Sqrt(In[i]).ToString("0.0000",local));
            }
        }
    }
}
