No

Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

namespace ITP1 {
	class Program {
		public static void Main() {
			int[] input = Console.ReadLine()
				.Split()
				.Select(int.Parse)
				.ToArray();
			int a = input[0], b = input[1], c = input[2];
			if (a < b && b < c) Console.WriteLine("Yes");
			else Console.WriteLine("No");
		}
	}
