Assume one file has r =106 records. each record takes r = 100 bytes, of which 10 bytes are for the key of the record. suppose the key values range from 1 through 1,000,000, inclusive. assume the block size b is 1000 bytes for all files, and that an address (block pointer, tree node pointer, or data record pointer) takes 10 bytes.
3. multilevel index: (15 points)
i. what is the fan-out value if multi-level index is used?
j. how many levels are there so that top level index fits on a single block in multilevel index?
k. how many block accesses are needed to fetch a record by using multilevel index?
l. what is the key value of the 4th index record on the top level, assuming each index record points to the record with the highest key value in a block of the next level down?

The program below has been generalized to read a user's input value for hourlywage. run the program. notice the user's input value of 10 is used. modify that input value, and run again. generalize the program to get user input values for workhoursperweek and workweeksperyear (change those variables' initializations to 0). run the program. monthsperyear will never change, so define that variable as final. use the standard for naming final variables. ex: final int max_length
