caute decka
vyfasoval som zadanie c2 ktore vyzera nejak takto a {ab} b [aa|bb]
vydumal som nieco taketo co mi bohuzial velmi nechce ist ;(
s0 @a {ab} b [aa|bb] -->S1
s1 a {@ab} @b [aa|bb] -->S2|S3
s2 a {a@b} b [aa|bb] -->S1
s3 a {ab} b [@aa|@bb]@ -->S4|S5|S6
s4 a {ab} b [a@a|bb] -->S6
s5 a {ab} b [aa|b@b] -->S6
s6 a {ab} b [aa|bb]@ -->fine
