On the first pass of the PCY Algorithm we use a hash table with 11 buckets, and the set {i, j} is hashed to bucket i xj mod 11. (a) [5 points] Which buckets are frequent? (b) [5points] Which pairs are counted on the second pass of the PCY Algorithm? Each contains three of the six items 1 through 6.
