Using the algorithm described in Section 4.4.2, remove direct left recursion form the following grammar rules. A → Aa | Abc | bc | d
Homework Answers
A -> Aa | Abc | bc | d
we can remove the left recursion by introducing a new entity, A' . where:
A -> bcA' | dA'
A' -> bcA' | aA' | e [e - corresponds to the 'ending']

Convert the following grammar into Chomsky Normal Form
(CNF):
S → aS | A
| bS
A → aA |
bBa | aAa
B → bb |
bBb
Note: you need to first simplify the grammar ( remove any
λ -
productions, unit productions, and useless productions), and then
convert the simplified grammar to CNF.
