No

Solution in C# (judge verdict: Accepted)

public partial class IntroductionToProgramming{
	public static void Main(){
		string[] line = System.Console.ReadLine().Split(' ');
		int a = int.Parse(line[0]);
		int b = int.Parse(line[1]);
		int c = int.Parse(line[2]);
		
		System.Console.WriteLine(a < b && b < c ? "Yes" : "No");
	}
