A file F is indexed by a clustered B+tree with Alternative 2 for data entries, and the B+tree has 5 levels with the root at level 1. What is the maximum size (in number of data pages) of the file F that can be indexed by the B+tree, and what is the worst I/O cost of finding the records with the search key value k if we do not use the B+tree? You can assume that each page can contain the maximum of 99 index entries (thus, 100 branches), the maximum of 1000 data entries, and 100 data records
