Four processes (P1, P2, P3, and P4) are sharing four resources (R1, R2, R3 and R4) in a system. The system has a total of 2 instances of R1, 2 instances of R2, 3 instances of R3, and 2 instances of R4. These processes have resource allocation as descried by the following Allocation matrix. Their resource demands are represented with the Request matrix. a) Can you leverage the deadlock detection algorithm to determine if the system has a deadlock? Be sure to show detailed steps to justify whether each process is able to complete and which processes, if any, are involved in the deadlock. b) Now P2 makes another request for one more instance of R2. Can you again leverage the deadlock detection algorithm to determine if the system has a deadlock? Be sure to show detailed steps to justify' whether each process is able to complete and which processes, if any, are involved in the deadlock
