Consider the following snapshot of a system:

Allocation Max Available

A B C D A B C D A B C D

P0 0 0 12 0 0 1 2 1 5 2 0

P1 1 0 00 1 7 5 0

P2 1 3 54 2 3 5 6

P3 0 6 32 0 6 5 2

P4 0 0 1 4 0 6 5 6

Answer the following questions using the banker’s algorithm:

a. What is the content of the matrixNeed?

b. Is the system in a safe state?

c. If a request from process P1 arrives for (0,4,2,0),can the request be granted immediately
