Consider the following snapshot of a system: Process Allocation Max Available
A B C D A B C D A B C D
P0 1 2 0 1 1 6 6 2 0 2 2 0
P1 1 0 0 1 1 1 0 1
P2 0 4 4 0 1 4 4 2
P3 0 0 0 2 0 0 2 3
P4 1 0 0 1 3 7 4 4
a) Is the system in a safe state (Use algorithm to show it)?
b) Is a request from Process P4 arrives for (0, 1, 0, 0) can the request be granted immediately (Use the data to show it)?
c) Is a request from Process P4 arrives for (0, 0, 1, 0) can the request be granted immediately (Use the data to show it)?
