WebClearly, if the table has N entries and each entry contains at most one item, you can iterate through all the items in time Θ ( N). Now, if N is some fixed constant, Θ ( N) time is constant time – and the set has constant size. On the other hand, if N is some variable that depends on the length of the input, then all the bets are off.
