Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        int[] arr = Console.ReadLine().Split().Select(int.Parse).ToArray();
        int a = arr[0];
        int b = arr[1];
        int c = arr[2];
        if (a < b && b < c)
        {
            Console.WriteLine("Yes");
        }
        else
        {
            Console.WriteLine("No");
        }
    }
