Solution in C# (judge verdict: Accepted)

using System;


namespace ConsoleApplication13
{
    class Program
    {
        static void Main(string[] args)
        {

            string[] s = Console.ReadLine().Split(' ');
            int a = int.Parse(s[0]);
            int b = int.Parse(s[1]);
            int c = int.Parse(s[2]);
            if (a < b)
            {
                if (b < c)
                {
                    Console.WriteLine("Yes");
                }
            }
            else
            {
                Console.WriteLine("No");

            }
            if (a < b)
            {
                if (b > c)
                {
                    Console.WriteLine("No");

                }
            }
