Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

public class Hello
{
    public static void Main()
    {
        int[] num = Console.ReadLine().Split(' ').Select(int.Parse).ToArray();

        if(num[0] < num[1] && num[1] < num[2])
        {
            Console.WriteLine("Yes");
        }
        else
        {
            Console.WriteLine("No");
