Problem 2 - Client Centric Consistency Models (20 points): A client is the only reader and writer of a data item X. Client moves between locations L1 and L2. A server at each location has a replica of the item X and also stores X's local version number (generation). The client reads and writes are always performed locally. A read operation R also returns the local version number of the item X. The initial version number of each copy is equal to 0. A write W increments the (local) version number by 1. PW is an update operation to the remote copy (initiated after a local W). PW carries the version number of X and stores it with the update. The time line goes from left to right.

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.
