        int count;

        for (int i = 0; i < words.Length; i++)
        {
            count = 1;

            for (int j = i + 1; j < words.Length; j++)
            {
                if (words[i].Equals(words[j]))
                {
                    count = count + 1;
                    words[j] = "";
                }
            }

            if (!words[i].Equals(""))
            {
                Console.WriteLine("[" + count + "] " + words[i]);
            }
