Consider a system with three processes (P1, P2, and P3) and four resources (R1 has one instance, R2 has two instances, R3 has one instance, and R4 has three instances). The Snapshot at time Tx has the following situation: P1 holds one instance from Resource R2 and Request Resource R1 P2 holds Resource R1, one instance from Resource R2 and Request Resource R3   P3 holds Resource R3 and Request one instance from Resource R2   Draw the Resource Allocation Graph,   then check if the system in safe state or not? If yes? What is the safe sequence?
