Question: A system has five processes P1 through P5 and four resource types R1 through R4. There are 2 units of each resource type. Given that:

A system has five processes P1 through P5 and four resource types R1 through R4. There are 2 units of each resource type. Given that: P1 holds 1 unit of R1 and requests 1 unit of R4 P2 holds 1 unit of R3 and requests 1 unit of R2 P3 holds one unit of R2 and requests 1 unit of R3 P4 requests 1 unit of R4 P5 holds one unit of R3 and 1 unit of R2, and requests 1 unit of R3 Show the resource graph for this state of the system. Is the system in deadlock, and if so, which processes are involved?
