No

Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

namespace Sample
{
	class Program
	{
		static void Main(string[] args)
		{
			var array = Console.ReadLine().Split().Select(s => int.Parse(s)).ToArray();
			var a = array[0];
			var b = array[1];
			var c = array[2];

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