Consider a system with five processes PO through P4 and three resources types A, B, C. Resource type A has 16 instances, B has 13 instances and type C has 15 instances. Suppose at time to following snapshot of the system has been taken. 5 Max B 5 3 A 1 2 4 Available A 4 35 PO P1 P2 P3 Allocation B C 2 1 1 3 1 2 2 2 4 2 5 CONTO 4 5 6 | | 2 3 P4 a. compute the need matrix b. P2 makes a request for (2 1 1). Using Banker's algorithm find out is it safe to process this request
