        String str=sc.nextLine();
        String res="";
        str=str.toUpperCase();
        String []words=str.split(" ");
        int i;
        for(i=0;i<words.length-1;i++)
        {
            res += words[i].charAt(0) + ".";
        }
        res +=words[i].charAt(0) + words[i].substring(1).toLowerCase() + ".";
        System.out.println(res);
    }
