Let us see the DFA of Regular Expression a(a+b)*+bb(a)*.
Explanation of DFA
- 2 Accepted strings of length 1={a, no more possible strings}
- 4 Accepted strings of length 2={aa, bb, ab, no more possible strings}
- 2 Accepted strings of length 5={aaaaa, bbaaa, …. and many more similar strings }
- 2 Accepted strings of length 8={aabbaabb, bbaaaaaa, … and many more similar strings }
- 2 Accepted strings of length 10={aaaaaaaaaa, bbaaaaaaaa, …. and many more similar strings }
- 2 Accepted strings of length 15={aabbbbaaabbbabb,bbaaaaaaaaaaaaa, …. and many more similar strings }
- 2 Accepted strings of length 20={aaaaabbbbbbbbbbaaaaa,bbaaaaaaaaaaaaaaaaaa, …. and many more similar strings }
- 2 Accepted strings of length 25={aaaaaaaaaaaabbbbbbbbbbbbb, bbaaaaaaaaaaaaaaaaaaaaaaa, …. and many more similar strings }
- and many more similar strings
