Eachsmoker continuously makes a cigarette and smokes it. But to make a cigarette, asmoker needs three ingredients: tobacco, paper, and matches.

/*PROGRAM 1 – Semaphores - Multiprocessor operating systemsAssume there are three processes: Pa, Pb, and Pc. Only Pa can outputthe letter A, Pb B, and Pc C.Utilizing only semaphores (and no other variables) the processes aresynchronized so that the output satisfies the following conditions:a) A B must be output before any C's can be output.b) B's and C's must alternate in the output string, that is, after thefirst B is output, another B cannot be...
