2. Consider the following snapshot of a system: Allocation Max ABCD ABCD Po 3014 5117 P. 2210 3211 P2 3121 3321 P3 0510 4612 P4 4212 6325 Using the banker's algorithm, determine whether or not each of the following states is unsafe. If the state is safe, illustrate the order in which the processes may complete. Otherwise, illustrate why the state is unsafe. a. Available = (0,3,0,1) b. Available = (1,0,0,2)
