class Program
{
    public static void Main()
    {
        string word = Console.ReadLine();
        int count = 0;
        while(true)
        {
            string[] str = Console.ReadLine().Split(' ');
            for(int i = 0;i < str.Length;i++)
            {
                if(str[i].ToLower() == word.ToLower())
                {
                    count++;
                }
            }
            if(str[0] == "END_OF_TEXT")break;
