PLEASE ANSEWER QUESTION $6$ ONLY

Add the method clone to the ArrayBag and LinkedBag classes. This method expects

no arguments when called, and returns an exact copy of the type of bag on which it is

called. For example, the variable bag$2$ would contain the numbers $2,3,$ and $4$ at the

end of the following code segment:

bag$1=$ArrayBag$([2,3,4])$

bag$2=$ bag$1.$clone $()$

bag$1==$ bag$2$ # Returns True

bag$1$ is bag$2$ # Returns False

A set is an unordered collection with the same interface as a bag. However, the items

in a set are unique, whereas a bag can contain duplicate items. Define a new class

named Arrayset that implements an array$-$based set type. The add method simply

ignores the item if it's already in the set.
