        {
            var W = Console.ReadLine();
            var count = 0;
            var line = "";
            while ((line = Console.ReadLine()) != "END_OF_TEXT")
            {
                var words = line.ToLower().Split();
                foreach (var item in words)
                {
                    if (item == W) ++count;
                }
