Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

namespace AizuOnLine
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] data = Console.ReadLine().Split(' ');
            int num1 = Convert.ToInt32(data[0]);
            int num2 = Convert.ToInt32(data[1]);
            int num3 = Convert.ToInt32(data[2]);

            if (num1 < num2 && num2 < num3)
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }
        }
    }
