namespace GinktageConsoleApp
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            int input;
            int result = 0, temp;

            while (input != 0)
            {
                result = result * 10;
                temp = input % 10;
                result = result + temp;
                input = input / 10;
