Solution in C# (judge verdict: Accepted)

using System;
using System.Text;

namespace AOJ_Hello_World {
	class Program {
		static void Main (string[] args) {
			var sab = Console.ReadLine();
			long[] a = new long[3];
			for (int i = 0;i < 3;i++) {
				a[i] = long.Parse( sab.Split(' ')[i]);
			}

			if(a[0]<a[1] && a[1] < a[2])
				Console.WriteLine("Yes");
			else
				Console.WriteLine("No");
		}
	}
