using System;

namespace AizuOnlineJudge
{
    class Program
    {
        static void Main(string[] args)
        {
            var array = Converter(Console.ReadLine());
            Console.WriteLine(Calc(array));
            Console.ReadLine();
        }

        static int[] Converter(string str)
        {
            var array = str.Split(' ');
            return Array.ConvertAll(array, int.Parse);
        }

        static string Calc(int[] array)
        {
            string result = "No";
            if (array[0] < array[1])
                if (array[1] < array[2])
                    result = "Yes";
            return result;
        }
    }
