Complete the following program code to reflect the process precedence graph shown below (where c; refers to the code-i). This code basically consists of creating two processes in parallel: the first process executes program P, and the second process executes program Pz. You should use semaphores for that. Also, do not forget to declare and initiate the semaphore. C2 C3 Begin ParBegin P1, P2 ParEnd End Program P: Begin ci; c3; End Program P2: Begin C2; End Complete the following program code to reflect the process precedence graph shown below (where c; refers to the code-i).
