Context-Free Grammars First and Follow
Budget: ₹600 – ₹1,500 INR
For this task you will implement the algorithms computing the functions First and Follow in JAVA, for the variables of a given context-free grammar. Recall
that a CFG is a quadruple (V, Σ, R, S) where V and Σ are disjoint alphabets (respectively,
containing variables and terminals), R ⊆ V ×(V ∪ Σ)∗
is a set of rules, and S ∈ V is the start
variable.
