1. Write a structurally recursive function named (curry exp) that takes one argument, a Racket lambda expression with n ≥ 1 formal parameters. curry returns a curried function. For example: > (curry (lambda (x) anything)) (lambda (x) anything) > (curry *(lambda (x) (lambda (y) (lambda (x y z) anything)) (lambda (z) anything))) curry does not process the function body, which can be any Racket expression. Hint: Make curry an interface procedure that passes the parameter list and the body (but not the symbol lambda!) to a structurally recursive helper function. The helper recurs on the parameter list, which is a list of symbols.

Transcribed Image Text:1. Write a structurally recursive function named (curry exp) that takes one argument, a Racket lambda expression with n ≥ 1 formal parameters. curry returns a curried function. For example:
> (curry '(lambda (x) anything))
'(lambda (x) anything)
> (curry '(lambda (x y z) anything))
'(lambda (x)
(lambda (y)
(lambda (z)
anything)))
curry does not process the function body, which can be any
Racket expression.
Hint: Make curry an interface procedure that passes the parameter list and the body (but not the symbol lambda!) to a structurally recursive helper function. The helper recurs on the parameter list, which is a list of symbols.
