    String s = sc.nextLine();
    String originalString = s;

    int vowelCount = 0;

    for (int i = 0; i < s.length(); i++)
    {
      char c = s.charAt(i);
      if (    (c == 'A') || (c == 'a')
           || (c == 'E') || (c == 'e')
           || (c == 'I') || (c == 'i')
           || (c == 'O') || (c == 'o')
           || (c == 'U') || (c == 'u') ){
        String front = s.substring(0, i);
        String back = s.substring(i+1);
        s = front + "*" + back;
      }
    }
    System.out.println();
    System.out.println(originalString);
    System.out.println(s);
  }
