Solution in C# (judge verdict: Accepted)

using System;

namespace AOJ
{
    class Program
    {
        static void Main()
        {
            string[] line = Console.ReadLine().Split(' ');
            int x = int.Parse(line[0]);
            int y = int.Parse(line[1]);
            int z = int.Parse(line[2]);

            string output = (x < y && y < z) ? "Yes" : "No";

            Console.WriteLine(output);
        }
    }
}
