Write an outputHashTable( ) method for the HashTable class that outputs

every item stored in the hash table.

Write a method named difference that returns the difference between two

sets. The method should return a new set that has items from the first set that

are not in the second set. For example, if setA contains {1, 2, 3, 4} and setB

contains {2, 4, 5}, then setA.difference(setB) should return the set {1, 3}.
