Problem . A system with two processors of unknown speed, the following two processes run in parallel. Assuming that each of the 10 instructions a - is atomic, list all the different possible pairs of outcomes (for xy) that can be produced by this code fragment. Show each sequence and outcome. The shared variables x.y both are initialized to O, and the shared semaphore mutex has initial value Process 2 b) wait(mutex) So g) wait(mutex)? h)y y- \veka e) signal(mutex,"#2 signal(mutex)
