Question

Consider that we have 3 groups of processes (group 1, group 2 & group 3).

  • Only one process can be executing in its critical section from group 3, provided that no processes are executing in their critical sections form groups 1 and 2.
  • At most 10 processes can be executing in its critical sections from group 2, provided that no processes are executing in their critical sections form groups 1 and 3.
  • An infinite number of processes can be executing in its critical sections from group 1, provided that no processes are executing in their critical sections form groups 2 and 3.

You should modify the code for the readers.writers problem.
