Solution in C# (judge verdict: Wrong Answer)

using System;

namespace Project
{
	class MainClass
	{
		public static void Main(string[] args)
		{
			string s = Console.ReadLine();
			string[] sar = s.Split(' ');
			int a = int.Parse(sar[0]);
			int b = int.Parse(sar[1]);
			int c = int.Parse(sar[2]);
			if (a < b)
			{
				if (a < c)
				{
					if (b < c)
					{
						Console.WriteLine("Yes");
					}
				}
			}
			else
			{
				Console.WriteLine("No");
			}
		}
	}
