Question 4. (1+2+2 points) Consider the following concurrent program with three processes, which may terminate only when the await statement has been executed. Answer Questions (a), (b) and (c). int x = 2, y = 3, z = 4; co // while (y == 3) } // while (z == 4) { 1000) x = 8;> } (a) In the above concurrent program, which atomic action is a conditional atomic action? Which condition is a delay condition? (b) Will the program be guaranteed to terminate if the scheduling policy is weakly fair? Justify your answer clearly. (c) Will the program be guaranteed to terminate if the scheduling policy is strongly fair? Justify your answer clearly
