        static void Main(string[] args)
        {
            var lines = File.ReadAllLines("text.txt");
            foreach (var l in lines)
            {
                var tokens = l.Split(' ');
                if (int.TryParse(tokens[0], out var a) && int.TryParse(tokens[1], out var b))
                    Console.WriteLine($"\t{a}\t{b}");
