Two design patterns are coupled when at least one class is a participant in both design patterns.
a) Draw a UML class diagram that clearly shows the coupling. Please identify which class(es) participates in multiple patterns.
b) Draw a UML Sequence diagram where you demonstrate the behavior of an instance of the coupled class from the perspective of one pattern, then from the perspective of the other pattern.
