Only need help with implementing (.cpp) the last two functions (toString() & intersectionWith()) Thanks!

Set A Set is a collection that can hold an arbitrary number of items. It however will only hold one copy of a given item (if you add 1 to the set f1, 2, 3) you still have (1, 2,3) Create a set that can be used like this: Setkint> mySet; mySet.add(13); mySet.add(12); mySet.add(13); cout & other) const-member operator. Returns true if the two sets contain exactly the same items. The items do not have to be in the same positions. [1, 2, 3] is string toString() const - returns a string that looks like (1, 2, 31 containing the items in the set. An empty set should return Note that you can instead provide an overloaded stream insertion operator. Comment out the test of the one you do not provide . Set intersection With(const Set& other) const- returns a new Set containing the items that are in both this set and the other set
