A nurse is cаring fоr а client whо hаs multiple traumas fоllowing a motor-vehicle crash. The spouse, who was driving the vehicle, blames themself for the accident. Which of the following responses should the nurse make?

Dr. Z аnd Ms. L аre cоllаbоrating оn a document. Develop a solution for synchronizing Dr. Z and Ms. L processes (PZ and PL) so that their concurrent accesses to the document do not mess it up. This problem shares similarities with the readers-writers problem that we discussed in class. So we show the solution to the readers-writers problem here for your reference. But pay attention to the differences. Copy-and-paste of the original solution may not work. Reference: solution to the readers-writers problem // Shared data structures semaphore rw_mutex = 1; semaphore mutex = 1; int read_count = 0; Reader process Writer process while(TRUE) { wait(mutex); read_count++; if (read_count == 1) wait(rw_mutex); signal(mutex); // reading wait(mutex); read_count--; if (read_count == 0) signal(rw_mutex); signal(mutex); } while(TRUE){ wait(rw_mutex); //writing signal(rw_mutex); } A) [10pts] Assume PZ and PL both can be reading and writing the document. A process can read regardless of whether the other process is reading or writing. When a process is writing, the other process cannot be writing at the same time. Fill in the placeholders in the algorithm below to complete your solution. // define your shared data structures here PZ PL while(TRUE) { if (reading) { // process wants to read // your code here } elseif (writing) { // process wants to write // your code here } } // you can skip PL’s code if it is identical to PZ B) [10pts] Now we add another mode of the processes to the system. In addition to reading and writing, PZ and PL can also be commenting the document. A process can still read regardless of the mode of the other process. Two processes can be commenting at the same time. When a process is writing, the other process cannot be either writing or commenting at the same time. Fill in the placeholders in the algorithm below to complete your solution. // define your shared data structures here PZ PL while(TRUE) { if (reading) { // process wants to read // your code here } elseif (commenting) { // process wants to // comment // your code here } elseif (writing) { // process wants to write // your code here } } // you can skip PL’s code if it is identical to PZ
