            }

            char[] arr = str.ToCharArray();
            Array.Reverse(arr);
            //Array.Sort(arr);

            // Reverse() is a Linq function
            //char[] reversed = str.Reverse().ToArray();
            //reversed.ToString();

            return new string(arr);
