Four processes (P1, P2, P3, and P4) are sharing three resources (R1, R2 and R3) in a system. The system has a total of 9 instances of R1, 3 instances of R2 and 6 instances of R3. These four processes' initial resource demands are represented with Matrix M. At time T_1, these processes have resource allocation as described by Matrix A. a) Can you leverage the safety assessment algorithm to evaluate whether each process is able to complete and eventually if the system is safe? Be sure to show the detailed steps. b) If PI now makes a request for one instance of R1 and one instance of R3, using deadlock avoidance algorithm please determine whether this request will be granted or not. Be sure to show the detailed steps
