So now, I would like for you to tell me
which of the following can be considered bad smells in
the context of refactoring. The fact that the program takes
too long to execute? The fact that method M in class
C is very long? Or the, the fact that Class
Cat and Dog are subclasses of class Animal? Or finally the
fact that every time we modify method M1 we also
need to modify method M2? So please mark all that apply.
