question 2

CFG corresponding to FA

S---bS|aA|^

A---aB|bS

B---ac|bc

C---ac|bB|^

is any mistake in it

according to me there will b a null string at B as well

moreover you have mixed terminals with non terminals

S---bS|aA|^

A---aB|bS

B---aC|bC|^

C---aC|bB|^

Dear @mohsin

agr B production k sath null ata hy to phr A production k sath b null ana chaye na qk A b ko read karty hwy S par jata hy or S final b hy

There is a null string at B stage bcoz it is a final stage and if one will read null string at B, it will still end up in B as it is a final stage, so string will be accepted as it is a final stage.

While A is a non final stage, if one will read a null string at A, it will still end up at A which is non final stage and string won't be accepted since it is a non final stage, that's why there is no null string at A.

Thanks.. :)
