Consider the following FAs with the regular expressions r 1 (for FA 1 ) and r 2 (for FA 2 ). By applying Kleenes theorem,
Consider the following FAs with the regular expressions r1 (for FA1) and r2 (for FA2).
By applying Kleenes theorem, an FA must be built for the regular expression r1r2. In the process a transition table is compiled. Which one of the following tables is the correct table in the solution for this problem?
- A.
