public class Hello{
    public static void Main(){
        var s = Console.ReadLine();
        s = s.ToLower();
        var ans = 0;
        while(true){
            var input = Console.ReadLine().Split(' ').ToList();
            if(input[0] == "END_OF_TEXT"){
                break;
            }
            var count = input.Select(x => x.ToLower()).Where(x => x.Contains(s)).Count();
            ans += count;
        }
        Console.WriteLine(ans);
