2. Consider the following query Q with tables T and S whereSize of T: 2000 pages I'O for a full table scan, 200 tuples per pageSize of S: 1000 pages I/O for a full table scan, 100 tuples per pageO: SelectFrom I. SWhere T.Sid = S.Sid:B+ Index is built on Sid of T where B+ tree level p is 3 to find a matching for the join condition:T.Sid (as FK) = S.Sid (as PK).Assume that Sid of T is uniformly distributed, average 4 matching Sid of I per Sid of S (i.e., Ave 4 unclusteredmatching for duplicates)What is the cost of Join with the table Tas inner and the table S as outer table to process the query O ahove

- MAC Datamining Exercise: Consider the following set of candidate 3-itemsets: {1, 2, 3}, {1, 2, 5}, {1, 3, 5}, {1, 5, 6}, {2, 3, 4}, {2, 3, 5}, {2, 4, 5}, {2, 4, 6}, {3, 4, 5}, {3, 4, 6} (a) Construct a hash tree for the above candidate 3-itemsets. Assume the tree uses a hash function where all odd-numbered items are hashed to the left child of a node, and all even-numbered items are hashed to the right child of a node. A candidate itemset is inserted into the tree by hashing on each successive item in the candidate and then following the appropriate branch of the tree according to the hash value. Once a leaf node is reached, the candidate is inserted based on one of the following conditions: If the depth of the leaf node is 3 (the root is assumed to be at depth 0), then the candidate is inserted regardless of the number of itemsets already stored at the node. If the depth of the leaf node is less than 3, then the candidate can be inserted as long as the number of itemsets…arrow_forwardH.W: Show the result of inserting 10, 12, 1, 14,6, 5,8, 15,3,9,7, 4, 11, 13, and 2, one at a time, into an initially empty binary heap?arrow_forwardGiven a max-priority queue A = <8, 5, 7, 3, 2, 4, 1>, consider calling Max-Heap-Insert(A, 6).

- a. Show how to implement a queue with two ordinary stacks so that the amortized cost of each Enqueue and Dequeue operation is O(1). b. Consider an ordinary min-heap supporting operations Insert and Extract-min that each costs O(lg n) worst-case time complexity when there are n items in the heap. Give a potential function Φ such that the amortized cost of Insert is O(lg n) and the amortized cost of Extract-min is O(1). Show Φ yields these amortized time bounds (n is the number of items currently in the heap and the size of the heap is unknown). Note: “Show” means to provide a proof with logical and precise arguments and/or derivations.arrow_forwardCreate a programme that does a range search on all components that fall between bounds a, b along a dimension i of the multidimensional data collection, represented as a k-d tree.Given the data collection (7, 5), (4, 2), (6, 8), (1, 4), (3, 5), (2, 4), (3, 7), (9, 1), (6, 6), (5, 1) expressed as a k-d tree (k = 2), a range search of data components falling inside (a = 3, b = 7) along dimension i = 2 produces (7, 5), (1, 4), (3, 5), (3, 7), (6, 6).arrow_forwardConsider the following data entries: 21, 24, 4, 10, 30, 34, 12, 13, 16.
