b* + b* (a(bb)+)* ab*
the restriction is only on a means if there are 2 a's side by side then there should be 2 b's b/w them rt ?
but if there is no a in the language then there is no restriction on b. So question is how can we generate only b , bb ,bbb...... out of this regular expression ?
from the given RE which is b*+b*(abb+)*ab* how can we get rid-off this a
Please tell me is this argument is right or wrong ...I'm so confused with RE
yes...b,bb,bb....can be generated...clear ur doubt
assume R.E ====> A+B means we can either take A or B at a time but not both...for generating any string..
and A* + B*/////means we can either take A any no.of time or B any no.of time but not both...for generating any string..
and ( A + B)*///brackets are important..means we can either take A any no.of time or B any no.of time or BOTH...for generating any string..
if we write (a,b)^+ or (aUb)^+ or (a+b)^+ does they all mean same ?
