Suppose you must perform three tasks, A, B, and C, that can be performed in any order (but not simultaneously). Describe how this problem can be framed as a production system and draw its state graph....

Suppose you must perform three tasks, A, B, and C, that can be performed in any order (but not simultaneously). Describe how this problem can be framed as a production system and draw its state graph. How does the state graph in the previous problem change if task C must be performed before task B?
