(a) Write a context-free grammar for polynomials in x. Add semantic functions to produce an attribute grammar that will accumulate the polynomial’s derivative (as a string) in a synthesized attribute of the root of the parse tree.

(b) Replace your semantic functions with action routines that can be evaluated during parsing.
