Allocation Max Available

A B C A B C A B C

P0 0 1 0 7 5 3 3 3 2

P1 2 0 0 3 2 2

P2 3 0 2 9 0 2

P3 2 1 1 2 2 2

P4 0 0 2 4 3 3

Using the banker algorithm: a) What is the content of the Need matrix? b) Is the system in a safe state? If yes, in which sequence can all processes execute and finish. c) If P1 requests for (1,0,2). Can the request be granted? Please explain.
