Semaphore is a flexible process synchronization primitive. Use semaphores to solve the readers-writers problem. Specifically, readers and writers share some data. Readers have shared access to the data, but writers require exclusive access to the data. (1) Give the pseudo code for the readers. (2) Explain what is the potential problem with your solution. Part of the code has been given

sem_t *read = sem_create(1);

sem_t *wrt = sem_create(1);

int read_count = 0;

Writer:

do { wait(wrt);

//write the shared data

...

signal(wrt);

}

while (TRUE)
