Problem 2. Assume that we use 2-level hashing where, at the second level, the hash table for a bucket with s elements is exactly s2. (a) Assume that n=2 (so there are two items and the first level of the hash table has size 2), what is the expected size of the storage for the second level? (b) Assume that n=3 (so there are three items and the first level of the hash table has size 3), what is the expected size of the storage for the second level
