(20 pts Total) Critical Sections a. (6pts) List and define the three requirements of a solution to the critical section problem. b. (8pts) Consider the proposed solution of the critical section problem listed below. Does the proposed solution meet each of the three requirements? Explain why or why not. Process B while (true) Process A while (true) { wait(mutex); //critical section signal(mutex); } wait(mutex); //critical section signal(mutex); } c. (6 pts) If the signal(mutex) call in process B is omitted? Will this change your answers from part b) above. Explain why or why not
