Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;
public class Hello{
    public static void Main(){
        int [] n = Console.ReadLine().Split(' ').Select(int.Parse).ToArray();
        if(n[0] < n[1] && n[1] < n[2]){
            System.Console.WriteLine("Yes");
        }else{
            System.Console.WriteLine("No");
        }
