Assume that we have a disk with 200 tracks, numbered 0-199, which is serving a request at track 123 and has just finished a request at track 115, The queue of requests is kept in the following FIFO order: 147, 95, 174 94, 128, 150, 102, 171, 111, 86, 120, 162, 70 Show the order of service {assuming no more requests} for SSTF, SCAN, and C-SCAN disk-scheduling algorithms
