- Copy the figure, mark the value of all the internal nodes, and indicate the best move at the root with an arrow.For non-unique search keys, a property was added. How does this affect B+ tree height?Which node of the B-tree index contains ROWIDs?a. branch blocksb. root blockc. leaf blocksd. None of the above because the primary key is used to identify rows
- Which data structure can be used to implement a hash table?* LinkedList and Tree LinkedList All of the above Array TreeHow does a hash table function to boost productivity over a traditional list? Is there a chance that you might explain the problem?A hashtable was used throughout development.True or False For each statement below, indicate whether you think it is True or False. If you like, you can provide a description of your answer for partial credit in case you are incorrect. 4) Delete is O(1) in the worst case because there is no shift after removing the node 5) Update is O(n) because it needs to perform a search for the element in the list 6) In the delete algorithm, the “previous” node reference is needed in case the element is not found in the list
- How can productivity be improved when a hash table is used in place of a linear list? What might be the problem?the creation of it using a hashtable16.16 Increase the length of the all-pairs minimum distance method to keep track of the shortest path between nodes. 16.17 Explain why it is sometimes more efficient to compute the distance from a single source to all other nodes, even if the query is only partially answered.T is an empty hash table. The size of T is 4 and the hash function is h(key) = key mod 4. Draw the hash table T after inserting the following item one by one: 24, 30, 29, 39, 30, 15, 14, 33.
