        static void Main(string[] args)
        {
            string s = Console.ReadLine();
            string[] str = new string [s.Length];
            for (int i = 0; i < s.Length; i++)
            {
                str[i] = s.Substring(i, 1);
            }
            Array.Reverse(str);
            foreach (string item in str)
