Solution in C# (judge verdict: Accepted)

using System;

	class MainClass
	{
		public static void Main (string[] args)
		{
			string str = Console.ReadLine ();
			string[]spStr = str.Split(' ');

			int a = int.Parse (spStr[0]);
			int b = int.Parse (spStr[1]);
			int c = int.Parse (spStr[2]);

			if (a < b && b < c)
			{
				Console.WriteLine ("Yes");
			}
			else
			{
				Console.WriteLine ("No");
			}
		}
}
