Extend bag ADT by:

a$.$ Add the methods union, intersection, and difference to the bag ADT.

The union of two bags is a new bag containing the combined contents

of the original two bags. The intersection of two bags is a new bag

containing the entries that occur in both of the original two bags. The

difference of two bags is a new bag containing the entries that would

be left in one bag after removing those that also occur in the second.

b$.$ Implement union method for class ArrayBag.

c$.$ Implement intersect method for class ArrayBag.

d$.$ Imlplement difference method for class ArrayBag.
