Solution in C# (Mono 4.6.2.0) (judge verdict: Runtime Error)

using System;
using System.Linq;
class Program
{
    static void Main()
    {
        int[] input = Array.ConvertAll(Console.ReadLine().Split(),int.Parse);
        //int input=int.Parse(Console.ReadLine());
        //string a = Console.ReadLine();

        Console.WriteLine(Array.IndexOf(input,"a")>-1&& Array.IndexOf(input, "b")>-1 && Array.IndexOf(input, "c") >-1? "YES":"NO");
        Console.ReadLine();
    }
