Question

Convert the following CFG into an equivalent CFG in Chomsky Normal Form (CNF) – A → BAB | B | ε B → 00 | ε

Answer 1

Answer:

Explanation:

CNF doesn't allows ε-productions

first we've to eliminate ε-productions

A->B | AB | BA | BB | ε

B->00

the language contains ε so A->ε can't be eliminated

Eliminating unit productions

A->00 | AB | BA | BB | ε

B->00

Now converting to CNF

A->CC | AB | BA | BB | ε

B->CC

C->0
