Solution in C# (judge verdict: Accepted)

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            String x = Console.ReadLine();
            //???????????????????????£??\
            String[] array = x.Split(' ');

            //??°???????????´????????£??\
            int a = int.Parse(array[0]);
            int b = int.Parse(array[1]);
            int c = int.Parse(array[2]);

            //??????????????¨???
            if (a < b && b < c)
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }

        }
