5. Consider a system with a total of 150 units of memory, allocated to three processes as shown: Apply the banker's algorithm to determine whether it would be safe to grant each of the following requests. If yes, indicate a sequence of terminations that could be guaranteed possible. If no, show the reduction of the resulting allocation table. a) A fourth process arrives, with a maximum memory need of 60 and an initial need of 25 units - [3 pts ] ? b) A fourth process arrives, with a maximum memory need of 60 and an initial need of 35 units - [3 pts]
