Closed Pano po yung mag type ka ng number sa cmd then lilitaw ng words

public static string NumberToWords(int number)
{
   if (number == 0)
       return "zero";

   if (number < 0)
       return "minus " + NumberToWords(Math.Abs(number));

   string words = "";

   if ((number / 1000000) > 0)
   {
       words += NumberToWords(number / 1000000) + " million ";
       number %= 1000000;
   }

   if ((number / 1000) > 0)
   {
       words += NumberToWords(number / 1000) + " thousand ";
       number %= 1000;
   }

   if ((number / 100) > 0)
   {
       words += NumberToWords(number / 100) + " hundred ";
       number %= 100;
   }

   if (number > 0)
   {
       if (words != "")
           words += "and ";

       var unitsMap = new[] { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
       var tensMap = new[] { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

       if (number < 20)
           words += unitsMap[number];
       else
       {
           words += tensMap[number / 10];
           if ((number % 10) > 0)
               words += "-" + unitsMap[number % 10];
       }
   }

   return words;
