True or False A graph consists of vertices connected by edges, with the edges possibly having directions and weights. As the size of the clusters in a hash table grows, the hash table performance will decrease. A hash function transforms a range of key values into a range of index values. Double hashing is completed to address the occurrence of secondary clustering. Double hashing generates probe sequences that depend on the key. The Depth First Search (DFS) algorithm involves going as deep as possible away from the starting vertex before branching out to vertices that are closer to the starting vertex.
Insert key 63 into the following Max-heap, then delete key 70. Use your final result to answer the following questions (a) What is the index of the node containing key 60 in the resulting tree? (b) List the leaves from left-to-right in the resulting tree? Note: The root is considered to have index 0.
10. Construct a BST for the incoming keys: 52, 38, 27, 42, 65, 18, 72, 67, 88 Average number of records reads for the tree. What if the keys arrived in a different order? 27, 38, 52, 72, 18, 42, 67, 88, 65 Construct the BST and find the: Average number of records reads for the tree. The Average number of record reads varies depending on the ordering of the keys

B+ trees in DBMS plays an important role in supporting equality and range search. Construct a B+ tree. Suppose each node can hold up to 4 pointers and 3 keys. Insert the following 10 keys (in order from left to right): 1, 3, 5, 7, 9, 2, 4, 6, 8, 10 After the insertions, which of the following key pairs resides in the same leaf node? Refer to the previous question. How many pointers (parent-to-child and sibling-to-sibling) do you chase to find all keys between 4 and 7?
Consider the following BST: 50 65 23 Now you (1) add key 28 and then (2) add key 63. [Write your answer with a single space between the node contents) Print out the nodes with inorder traversal. Print out the nodes with preorder traversal. Print out the nodes with postorder traversal.
