Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            String s = Console.ReadLine();
            String[] strArr = s.Split(' ');

            int intA = int.Parse(strArr[0]);
            int intB = int.Parse(strArr[1]);
            int intC = int.Parse(strArr[2]);

            String strMessage = null;

            if (intA < intB && intB < intC)
            {
                strMessage = "Yes";
            }else
            {
                strMessage = "No";
            }

            Console.WriteLine(strMessage);
        }
    }
