- Draw this scenario on a piece of paper and answer what is required on the next items, upload an image of your graph here. A system has three processes (P1, P2, P3) and three reusable resources (R1, R2, R3). There is one instance of R1, two instances of R2 and three instances of R3. P1 holds an R1 and an R3 and is requesting an R2. P2 holds an R3 and is requesting an R1 and an R2. P3 holds two R2 and an R3 and is requesting an R1. (rating in this item will be manually encoded by the instructor upon checking)In this problem, we wish to build a repository of functions that a developer can assemble to build a complex program. There can exist several versions of a function, each with its metadata. Function metadata includes the developer's full name and email address, the language it is implemented in and a set of keywords related to the functionality fulfilled by the function. The versions of a function can be represented as a directed acyclic graph. To manage the repository, we use a remote invocation based GRPC that allows a client to interact with a server and execute the following operations: 1. add_new_fn: to add either a brand new function or a new version to an existing function; 2. add fns: to add multiple functions streamed by the client (note that multiple versions of a function are not allowed); 3. delete_fn: to delete a function (this might require reordering the versions of the function); 4. show_fn: to view a specific version of a function; 5. show all fns: to view all versions…Generate a BLP lattice–structured system where the objects and subjects are appropriately levelledto give access consistent with the access control matrix below.

The machine should check that each voter is eligible to vote. The electoral registrar will also want to print a summary of the total votes for each candidate, and (separately) a list of the voters who have voted, and a list of those who haven't. In case of a dispute, the machine should also list a complete record of who voted for whom, but only a judge can use this function.
