Question

Write a synchronization solution to the below scenario using semaphores only

please use the table i provided for the answer 

Answer: //Shared variables *Put your semaphores declaration & initialization below this line */ //Process 1 //Process 2 do { 7/Process 3 do{ do{ Code P1.1 Code P3.1 Code P2.1 Code pl.2 Code p3.2; Code pl.3 } while (true); }while (true) ; } while (true);

Assumptions: The arcs in the chart below illustrate the processes dependencies. The CPU can start with any process [keep in mind that always the subprocesses execute in a sequential order ex: the CPU never select to execute p2.2 before p2.1]. The semaphores are used to ensure that the processes will execute in any sequence but within the suggested dependencies in the chart. Code Code Code Code Code P3.1 P2.1 P1.2 P3.2 P1.3 Code P1.1
