Question
Question 2 The diagram below shows a B- tree after the root node has been split and a new node is created above it, increasing the height of the tree. A new node containing the key H is created as the parent of the two nodes split from the original root node. H JL А В EFG M N K a) Reconstruct the B - tree after deleting the key K. 3 b) After deleting the key K from the B - tree shown, this is no longer a valid B-Tree because there is no longer a middle child between the keys J and L. Demonstrate how to correct the structure by redistributing some of the keys among the children. c) Reconstruct the B- tree after the keys I and J were deleted bearing in mind that key K already deleted. Explain how to correct the tree structure as redistribution is required. d) B-Trees are specifically designed for managing indexes on secondary storage such hard disks, compact discs, and so on, providing efficient insert, delete, and search operations. Predict six characteristics of B- trees.
