1 Someone suggests that ArrayIndexedList should extend ArrayStack and LinkedIndexedList should extend LinkedQueue. Discuss the advantages and disadvantages of this proposal.
2 Define a method __eq__ for the ArrayIndexedList class. This method returns True if the two arguments are identical, or if they are of the same type, have the same number of items, and their items are equal at each position. Otherwise, the method returns False.
3 What is the running time of the __eq__ method, expressed in big-O notation?
