We have a disk that has 200 tracks and uses the elavator disk scheduling to serve requests for data on the disk tracks. Suppose at time 0, the scheduler has received requests for data on the following list/queue of tracks: 36, 69, 167, 76, 42, 51, 126, 12, and 199, in that order. If the r/w head is currently on track 100 and is moving to track 200, the request for data on which track will be served AFTER serving the one on track 76? Your answer is one of the tracks listed above.
