class LabProgram {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String s = scanner.nextLine();
        String[] words = s.split(" ");
        String firstName = words[0];
        String middleName = words[1];
        if (words.length == 2)
            System.out.println(middleName + ", " + firstName.charAt(0) + ".");
        else {
            String lastName = words[2];
            System.out.println(lastName + ", " + firstName.charAt(0) + "." + middleName.charAt(0) + ".");
