Tom has finally taken over the business empire and now looking for
a new Name of the business to make a new start.

Joe (Tom's dear friend) suggested a string $S$ consisting of
Uppercase and lowercase letters

Tom wants to make some changes as per the following criteria:

1) String should $not$ have any vowels .

2) Every other uppercase consonant(other characters except vowels) should
be in lowercase

For ex:

If the consonant character is Z then it should be z

3) There should be a character "." before each consonant.

Help Tom to make the required Changes.
