Consider the following two processes P1 and P2, to be run concurrently in a shared memory. The line numbers P11, P12 and P21, P22 have been added to the left of each statement. Shared variables int x=2, y=3 Process P1 Process P2 P11: x=x*y P12: y=x+y Assume that the assignments are executed atomically. How many different values of x are possible after both processes finish executing? What are those values? Show your work. (10 marks) P21: y=x+y P22: x=x*y
