Solution in C# (judge verdict: Wrong Answer)

using System;
using System.Collections.Generic;
class Program
{
	static void Main(string[] args)
	{
		string[] str = Console.ReadLine().Split(' ');
		int a = int.Parse(str[0]);
		int b = int.Parse(str[1]);
		int c = int.Parse(str[2]);
		string s = "";
		if(a < b && b < c){
			s = "YES";
		} else {
			s = "NO";
		}
		Console.WriteLine(s);
	}
}
