The r/w head of a disk is at track 143. The previous position was track 0. Requests to access the following tracks have arrived: 143, 86, 1470, 913, 1774, 948, 1509, 1022, 1750, 130 a. In which order will the tracks be visited using:
⢠FIFO
⢠SSTE
⢠Scan
⢠C-Scan

b. Starting from track 143, determine the number of tracks traversed by the r/w head under each algorithm to service all requests.
