using System;
     using static System.Console;
     class Sorting{
              static void Main()
              {

                       int num1, num2, num3;

                       string snum1, snum2, snum3;
                    Write ("Enter first number ");

                    snum1 = ReadLine();

                    num1 = Convert.ToInt32(snum1);

                    Write ("Enter second number ");

                    snum2 = ReadLine();

                    num2 = Convert.ToInt32(snum2);
                    Write ("Enter third number ");
                    snum3 = ReadLine();

                    num3 = Convert.ToInt32(snum3);
                    // here we have to check the sequence
                    // like num1 should be less than num2 and num2 should be less than num3
                    if (num1 < num2 && num2 < num3)
                             WriteLine ("Numbers are in sequential order");
                    else
                    // here we should check of descending order
                    // num1 should be greater than num2 and num3
                    if (num1 > num2 && num2>num3)
                        WriteLine ("Numbers are in reverse order");
                    else
                        WriteLine ("Numbers are in neither sequential nor reverse order");

           }

}
