Consider the following Racket term: (let ([x (f (+ x ( z a)))]) (g (f x))) Recall that a term is in ANF if function calls occur only (a) with atomic arguments and (b) directly under a single let binding. Recall that a term is in CPS if every function call is a tail call (including uses of builtins such as +). For the purposes of this problem, in the CPS portion, you may assume that builtins such as + take an extra continuation argument. (a) Write a translation of the above term to A-Normal Form (ANF). (b) Write a translation of the above term to Continuation-Passing Style (CPS).
