fifty pointers.

Suppose that blocks can hold either three records, ten key pointer pairs, or fifty pointers. Using the indirect-buckets scheme of Fig. 14.7:

a) If the average search-key value appears in 10 records, how many blocks do we need to hold 3000 records and its secondary index structure? How many blocks would be needed if we did not use buckets?

b) If there are no constraints on the number of records that can have a given search-key value, what are the minimum and maximum number of blocks needed?
