This question is about sparse and dense indexes. Suppose blocks either hold up to 30 records or 200 key-pointer pairs, and neither data- nor index-blocks are allowed to be more than 80% full. As a function of number of records n, how many blocks do we need to hold a data file for a dense index? Answer this question also for a sparse index.
