Using Python The mirror image of string vow is string wov, and the mirror image wood is string boow. The mirror image of string bed cannot be represented as a string, however, because the mirror image of e is not a valid character. Develop function mirror() that takes a string and returns its mirror image but only if the mirror image can be represented using letters in the alphabet. >>> mirror('vow') 'wov' >>> mirror('wood') 'boow' >>> mirror('bed') 'INVALID'.
