Suppose we minimize the average time to store files of lengths dots, on a tape. If the probability of requesting file is given by the expected access time to load these files in the order dots, is given by the formula The constant represents parameters such as the speed of the drive and the recording density. a In what order should a greedy approach store these files to guarantee minimum average access time? b Write the algorithm that stores the files, analyze your algorithm, and show the
