• The Cigarette-Smokers Problem.

The Cigarette-smokers problem: Consider a system with three smoker processes and one agent process. Each smoker continuously rolls a cigarette and then smokes it. But to roll and cigarette and then smokes it. But to roll and smoke a cigarette, the smoker needs three ingredients: tobacco, paper and matches. One of the smoker processes has an infinite supply of all the three materials. The agent places two of the ingredients on the table. The smoker who has the remaining ingredient then makes the smokes a cigarette, signaling the agent on completion. The agent then puts out another two of the three ingredients, and the cycle repeats. Write a program to synchronize the agent and the smokers.
