import java.io.*;
class Sentence{
    public static void main(String args[])throws IOException{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter the sentence: ");
        String s = br.readLine();
        s = s.trim();
        s = s.toUpperCase();
        String t = "";
        for(int i = 0; i < s.length(); i++){
            if(i == 0 || s.charAt(i - 1) == ' ')
                t += s.charAt(i) + ".";
        }
        System.out.println(t);
    }
}
