Hash-based set difference. Using hashing-based algorithm introduced in the textbook, compute r - s, where r is one-attribute relation with elements (3, 7, 20, 14, 11, 42, 28. 17) and s is one-attribute relation with elements (11, 10, 19, 17, 20). Suppose the hash function used for partitioning is h X mod 3, and the hash function used for building in-memory hash index is h2 X mod 7. Show your work (ie, detailed steps used in applying the algorithm to solving this particular problem) Hash-based set difference.
