In Bounded-buffer problem (all known as Producer-Consumer problem), how will the execution result be affected if wait (mutes) and signal (mutes) is removed, respectively? The structure of the producer process: do { .. /* produce an item in next_produced */ .. wait(empty): wait(mutex): .. /* add next produced to the buffer */ .. signal (mutex): signal(full): } while (true): The structure of the consumer process do { wait(full): wait(mutex): .. /* remove an item from buffer to next_consumed */ .. signal(mutex): signal(empty): .. /* consume the item in next consumed */ .. while (true)
