Follow the following algorithm to transform a Regular Expression into a Finite Automaton.

Start by placing the regular expression on the edge between a start and final state: 

Apply the following rules to obtain a finite automaton until all edges are labeled with either a letter or A (A-transition is the same as e-transition). (state i and state j could be the same state)

a) Use the above algorithm to construct an NFA for each of the following regular expressions over {a, b}. (An option for tools of drawing FA: https://madebyevan.com/fsm/)

    1. (a + b)*
    2. (a* + b*)*
    3. (a*b*)*

b) Do the above three regular expressions describe the same language? Explain your answer.
