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 guar-
anteed 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.
b. A fourth process arrives, with a maximum memory need of 60 and an initial need
of 35 units.
