(a) Consider that two processes, P1 and P2, are executing concurrently. Both the processes share a standard variable named "Counter", having an initial value =5. Find the final value of Counter and update tables below: - Process P1 tries to increment the value of the counter. - Process P2 tries to decrement the value of the counter. - Update column Reg 1, Counter and Reg 2 . i. The execution order of the instructions may be P1, P1, P2, P2. [5] (Notes: Column P1 with value 1 is produce 1 slot and column P2 with value 1 is consume 1 slot)
