Solution in C# (judge verdict: Wrong Answer)

using System;
using System.Linq;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] x = Console.ReadLine().Split().Select(int.Parse).ToArray();
            int r1,r2,r3;
            r1 = x[0];
            r2 = x[1];
            r3 = x[2];
            Array.Sort(x);
            if (r1 == x[0] && r2 == x[1] && r3 == x[2]) { Console.WriteLine("Yes"); }
            else { Console.WriteLine("No"); }

        }
    }
