Question 11 There are three cooperating processes. They all read data from the same input device. Each process, when it gets the input device, must read two consecutive data. (Hint: use mutual exclusion to achieve it). Using semaphores, what is the minimum number of semaphores that could be used to solve this situation. How many would be initialized to 0 and how many would be initialized to 1: Pl inpt(al.a2) P2: input (b1,b2) P3 nput(cl,c2) Print X) W-b2+c2 X-Z-Y+W O 7 initialized to 0 and 1 initialized to 1 O 1 initialized to 0 and 7 initialized to 1 O 5 initialized to 0 and 1 initialized to 1 O and 5 initialized to 1
