To implement the circular nature of the bounded$-$buffer problem, the producer fills the slot buffer$[$nextin$]$ and then increments nextain by $1$modn. Similarly, the consumer empties the slot buffer$[$next out$]$ and then increments nextwout by $1$modn.

a$)$ What problem would occur if multiple producers or multiple consumers executed the bounded buffer code?

B$)$ extend the bounded$-$buffer problem to allow mutiple producer and multiple consumer processes.
