Problem : Context free Grammar & derivation pts Contextfree grammars CFGs can be useful in various use cases. One such use case is to check on the syntax of the programming language and hence even now CFGs are used in Natural Language Processing NLP to help models interpret languages. Further, modernday IDEs are leveraging this use case to construct Syntax Highlighters.
Let's consider you are given a task to design the CFG for a very basic valid variable definition in
A couple of examples not exhaustive:
float ;
double sum ;
int ;
pts Create a contextfree grammar for the given task. Assume the operators are and the datatypes are int, float, double, long. For simplicity, we are excluding char or string data types.

Also, the operators and are only applicable with variable names.
Using the grammar generated in part provide the leftmost derivation of the expression:
