f the size of the AList grows beyond the underlying array$$s capacity, we need to allocate

a new, bigger array. Implement growIfNeeded and resize according to their specifi$-$

cations. Use the provided createArray method to perform the allocation in

growIfNeeded; then, resize can change the size of the list and call growIfNeeded to

expand the capacity as necessary. Your code should now also pass test$10$Resize.
