Question
![Translate the automaton below into a regular expression using the algorithm described above.
Note that the automaton already has a single initial and a single final state.
Please draw the automaton after each step. Here a step consists of:
• Removing all double arrows in the automaton.
• Removing one state.
Again, remove all double arrows.
It is important to follow the algorithm closely.
The regular expressions have the following syntax:
+ for union, . for concatenation and * for Kleene star
Aor L for A, the language containing only the empty word
e (zero) for Ø, the empty language
can often be left out
Example expression: abc*d(a +L + Obc)*c is short for a · b · c* · d · (a + A +Ø•b• c)* · c.
