Question

Let ∑ = {a,b}, and let L be the language over ∑:

L = w € ∑+
Give a context-free grammar (CFG) for L, and briefly explain how it works to correctly represent the language. There are no additional requirements for your solution other than what is stated here, except the usual guidance to make sure your answer is clear and understandable and avoids too much unnecessary complexity. In particular, there is no credit for the grammar being unambiguous (if possible.)

Answer 1

Step-by-step explanation:

From the information given, By applying a CFG for L:

Because each state generates two symbols or null, the length will be equal and even.

1st Condition:

throughout the first half, at least one (a)

2nd:

exactly one (b) within the second half
