Explаin if there аre аny lоgical errоrs including data-races and deadlоcks in the following code that implements the Readers-Writers Problem, where multiple readers are allowed to read from the database while only a single writer and in a mutually exclusive way with respect to the readers can write to the database. Assume that the mutex and the condition variables have been initialized properly and that numReaders and numWriters have been initialized to 0 before the threads are created. If you find any issues in the code below, then suggest how to fix the implementation. Reader ================= pthreads_mutex_lock(&mutex) while numWriters > 0           pthread_cond_wait(&reader, &mutex) numReaders++ pthread_mutex_unlock(&mutex) READ from the database pthread_mutex_lock(&mutex) numReaders-- pthread_cond_signal(&writer) pthread_mutex_unlock(&mutex)   Writer =================== pthread_mutex_lock(&mutex) while numReaders > 0           pthread_cond_wait(&writer, &mutex) numWriters++ pthread_mutex_unlock(&mutex) WRITE to the database pthread_mutex_lock(&mutex) numWriters-- pthread_cond_signal(&reader) pthread_mutex_unlock(&mutex)
