Consider using a bitmap versus a linked list of free blocks. The disk contains a total of B blocks, F of which are free. A disk address requires d bits. The bitmap uses one bit for each block. The linked list is a data structure maintained in a dedicated portion of the disk. Each list element points to a single free block. (a) State the condition under which the two methods use the same amount of disk space, assuming that the linked-list method connects all blocks individually.
(b) For d = 16 bits, determine the fraction of the disk that must be free for the above condition to hold.
(c) Repeat the two problems above, assuming that the linked-list method connects groups of adjacent blocks, rather than individual blocks. That means, each list element points to the first of block of a group, and contains a two-byte number indicating how many blocks are in the group. The average size of a group is five blocks.

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
