{
    class ITP1_2_B
    {
        static void Main(string[] args)
        {
            var str = Console.ReadLine().Split(' ');
            if (str.Length < 3)
                return;
            var a = int.Parse(str[0]);
            var b = int.Parse(str[1]);
            var c = int.Parse(str[2]);

            Console.WriteLine(a < b && b < c ? "Yes" : "No");
        }
    }
