Solution in C# (judge verdict: Accepted)

using System;

namespace ITP1_2_B
{
	class Program
	{
		static void Main(string[] args)
		{
			string[] vs = Console.ReadLine().Split(' ');
			int a = int.Parse(vs[0]);
			int b = int.Parse(vs[1]);
			int c = int.Parse(vs[2]);

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