Suppose the read/write head is at track 97, moving toward track 199 (the highest-numbered track on the disk) and the disk request queue contains read/write requests for sectors on track 84, 155, 103, 96, and 197, respectively. A) What is the total number of head movements needed to satisfy the requests in the queue using the first come first served (FCFS) optimization strategy?
B) What is the total number of head movements needed to satisfy the requests in the queue using the Scan optimization strategy?
C) What is the total number of head movements needed to satisfy the requests in the queue using the Look optimization strategy?

Anew author is in the process of negotiating a contract for a new romance novel. the publisher is offering three options. in the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published. in the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold. in the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000. the author has some idea about the number of copies that will be sold and would like to have an estimate of the royal- ties generated under each option. write a program that prompts the author to enter the net price of each copy of the novel and the estimated number of copies that will be sold. the program then outputs he royalties under each option and the best option the author could choose. (use appropriate named constants to store the special values such as royalty rates and fixed royalties.
