a. The values of Need for processes P0 through P4 respectively are (0,0, 0, 0), (0, 7, 5, 0), (1, 0, 0, 2), (0, 0, 2, 0), and (0, 6, 4, 2).
b. The system is in a safe state? Yes. With Available being equal to (1, 5, 2, 0), either process P0 or P3 could run. Once process P3 runs, it releases its resources, which allow all other existing processes to run.
c. The request can be granted immediately? This results in the value of Available being (1, 1, 0, 0). One ordering of processes that can
finish is P0, P2, P3, P1, and P4.
