Solution in C# (judge verdict: Accepted)

using System;

public class Sum
{
    private static void Main()
    {
        string[] abc = Console.ReadLine().Split(' ');
        int a = int.Parse(abc[0]);
        int b = int.Parse(abc[1]);
        int c = int.Parse(abc[2]);

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