Question

Given the following state of system: the system comprises of four processes and three resources.

P1 – P4 denotes the set of processes

R1 – R3 denotes the set of resources

Claim Matrix C

	R1	R2	R3
P1	4	5	3
P2	3	2	3
P3	1	2	3
P4	1	0	2

Allocation Matrix A

	R1	R2	R3
P1	2	2	0
P2	3	2	0
P3	1	1	3
P4	0	0	2

Available Matrix V

R1	R2	R3
0	3	2

Compute the Resource vector R. (08)
Compute the need Matrix

Is the current allocation state safe? If, give a safe sequence of the process. In addition, show how the Available (working array) changes as each process terminates.
