Please provide the correct answer for this question that is incorrect, explain why my answer is wrong and what I can do differently next time so that I can do better next time.
![P3 sets M3 before it reads it, so M3 is not in the domain.
Assume a system of 4 processes P = {P1, P2, P3, P4} and 5 memory cells M
All memory cells are initialed to 0 before any processes are started.
The processes implement the following instructions:
