So we only need to worry about step 3. Starting Grammar: S-> ABa A-> aab B-> Ac WebWhen we convert CFG to CNF, grammar does not have any λ – productions or any unit production. If it has λ – productions or any unit production we have to remove it. Let consider a grammar that has no λ – productions or any unit production. And we are going to convert it to the corresponding CNF production rule (V → VV T) Example:
