The given DFA is for the Regular expression of (bb)*(aa)*.

  • 2 Accepted strings of length 1= {No String Exist}
  • 2 Accepted strings of length 2= {bb, aa}
  • 2 Accepted strings of length 5= {No String Exist}
  • 2 Accepted strings of length 8= {bbbbaaaa, bbbbbbbb, …. and many more similar strings.}
  • 2 Accepted strings of length 10= {bbbbbbaaaa, bbaaaaaaaa, …. and many more similar strings.}
  • 2 Accepted strings of length 15= {No String Exist}
  • 2 Accepted strings of length 20= {bbbbbbbbbbbbbbbbaaaa, bbbbbbbbbbaaaaaaaaaa, …. and many more similar strings. }
  • 2 Accepted strings of length 25= {No String Exist}
  • and many more similar strings
