A system has four processes: P1, P2, P3, P4 and three resources: RS1, RS2, RS3. The allocation and request matrices are: Allocated RS1 RS2 RS3; Requested RS1 RS2 RS3. P1: Allocated (1,0,1), Requested (2,0,0); P2: Allocated (2,1,0), Requested (1,1,1); P3: Allocated (0,2,2), Requested (2,1,0); P4: Allocated (1,0,1), Requested (0,2,1). Available resources: (1,1,1). Is the system in a safe state?
