Show how to implement a dictionary in external memory, using an unordered sequence so that insertions require only O(1) transfers and searches require O(n/B) transfers in the worst case, where n is the number of elements and B is the number of list nodes that can fit into a disk block.
Describe a modified version of the B-tree insertion algorithm so that each time we create an overflow because of a split of a
node v, we redistribute keys among all of v's siblings, so that each sibling holds roughly the same number of keys (possibly cascading the split up to the parent of v). What is the minimum fraction of each block that will always be filled using this scheme?
