Let's consider the environment of a nursery school where regulations require that one teacher per R children is always present, where R is an integer, in order to ensure proper supervision of children. Moreover, we would wish for our configuration to have the following characteristics: 1. If a teacher attempts to leave but this is not possible, he should returns in office (and not block while waiting for the exit condition to be met) 2. Every parent should be able to enter the nursery area to verify whether the regulation is met. Please provide the synchronized processes: Teacher, Children, Parents, which satisfy the requirements above, by further defining functions:_enter, _exit ), verify_compliance () shown below, or by replacing the latter functions with the proper synchronization code within: Teacher), Child) and Parent (). You may use mutexes/ locks, semaphores, shared variables). void Teacher() void Child) void Parent) for (G:) f for G:) for (3) child enter); ...critical section learn); child exito go hone) teacher_enter); parent enter; critical section teach); teacher exit); go home) critical section verify_compliance) parent exit); go home)
