Solution in C# (judge verdict: Accepted)

using System;

using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp6
{
	class Program
	{
		static void Main(string[] args)
		{
			string abc = Console.ReadLine();
			string[] num = abc.Split(' ');

			int a = int.Parse(num[0]);
			int b = int.Parse(num[1]);
			int c = int.Parse(num[2]);

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