using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var ab = Console.ReadLine().Split().Select(x => int.Parse(x)).ToArray();
            var a = ab[0];
            var b = ab[1];
            var c = ab[2];
            if (a < b)
            {
                if (b < c)
                {
                    if(a< c)
                    {
                        Console.WriteLine("Yes");
                    }
                    else
