Suppose a system in which there are two types of processes, type A processes and type B processes. All processes of type A execute the same code, and all processes of type B execute the same code. The code for each process type is shown below. Process A wait(Y) wait(Y) signal(X) signal(Y) Process B wait(X) signal(Y) Here, X and Y are general semaphores. X is initialized to 2, and Y is initialized to 0. Suppose three processes of type A and two processes of type B are brought into execution simultaneously. Answer the following two questions: a) Is it possible for processes to finish in the order of BBABA? If so, show an execution sequence that results in this order. If not, explain why. (show the semaphore values in each process run) b) Is it possible for processes to finish in the order BBAAB. If so, show an execution sequence that results in this order. If not, explain why. (show the semaphore values in each process run) Suppose a system in which there are two types of processes, type A processes and type B processes.
