Concatenation

Regex : /^AB$/ Psuedo: start str(AB) end

Machine:

->o --A--> o --epsilon--> o --B--> (o)

Submachine_A --epsilon--> Submachine_B

Union

Regex : /^A|B$/ Psuedo: start glyph(A) | glyph(B) end

Machine:

    epsilon--> o --A--> o --epsilon
   /                               \
->o                                 ->(o)
