Suppose, there are three producers P1, P2, and P3 who want to produce and put items in the buffer. And, there are four consumers C1, C2, C3, and C4 who want to consume items from the buffer. No process takes more than 5 units of time to complete unless the process goes to the waiting queue(S->list) of semaphore. At a certain point of the execution, following are the values of the semaphores: mutex=1, countEmpty38, countFull=2 Find the output of the following sequence of commands.
