et's say you are writing a parsing function in Racket for the following set of productions. → BaA | bAB |A ou've decided that "a" predicts A → BaA, "b" predicts A→ bAB, and "c" predicts A→ A. Any oth ext input (including $) indicates an error. Complete the function below by filling in the blanks wi hat should replace the # 1, #2, #3 and #4 in the code. n your answers use exactly one space between parameters in function calls. For example, (foo (E D). You may call functions parseA, parseB, and match in your answers. Follow the conventions se n class. (define (parseA toks) (cond ((not (list? toks)) false) (Cempty? toks) #1) ((equal? (first toks) "a") #2 ) (Cequal? (first toks) "b") #3 )
