Plus Minus

    Why your "N" a float , it is the length of the Array and i think it must be integer because you can't an Array with 2.5 in size !!!

      Because, in Python, if you divide two ints, you would get the result of the integer division, in this case 0. But if the N is stored as a float, you are already forcing the floating point division here.

        To my knowledge, that is only the case for Python 2. Python 3 returns the fractional part as well even if you divide two ints. :)

          yeah I think that's right

          Right, in python3 if you dont want the fraction just use floor division a//x.

        In C# as well. Took me "forever" to find out.

          int n = Convert.ToInt32(Console.ReadLine()); string[] arr_temp = Console.ReadLine().Split(' '); int[] array_temp= Array.ConvertAll(arr_temp,Int32.Parse); int PositiveNumbers= array_temp.Where(x=>x>0).ToList().Count; int NegativeNubers=array_temp.Where(x=>x<0).ToList().Count; int zeroNumbers=array_temp.Length-(PositiveNumbers + NegativeNubers);

               decimal Pos=(decimal)PositiveNumbers / n;
      decimal Neg=(decimal)NegativeNubers / n;
      decimal Zer=(decimal)zeroNumbers / n;

      Console.WriteLine( string.Format("{0:0.000000}",Pos));
    Console.WriteLine(string.Format("{0:0.000000}",Neg));
     Console.WriteLine(string.Format("{0:0.000000}",Zer));

        you could also import division from future which fixes the integer and float division as in Python 3.
