> The size, isEmpty, get, set, iterator, and listIterator operations run in constant time.
The add operation runs in amortized constant time, that is, adding n elements requires O(n)
time. All of the other operations run in linear time (roughly speaking). *The constant factor
is low compared to that for the LinkedList implementation.*
