Exercise 182: Eliminate quote from the following expressions

Exercise 182: Eliminate quote from the following expressions

Eliminate quote from the following expressions so that they use list instead:

1. '(1 "a" 2 #f 3 "c")
2. '()
3. and this table-like shape:

   '(("alan" 1000)

   ("barb" 2000)

   ("carl" 1500)

   ("dawn" 2300))

   
   
   

   Now eliminate list in favor of cons where needed.

Eliminate in favour of list

This is very straight forward.

(list 1 "a" 2 false 3 "c")
(list)
(list (list "alan" 1000)
      (list "barb" 2000)
      (list "carl" 1500)
      (list "dawn" 3000))

Eliminate in favour of cons

This is not hard, but painful. Constructing lists like this is frustrating - which is the point of the exercise.

(cons 1 (cons "a" (cons 2 (cons false (cons 3 (cons "c" empty))))))

empty


(cons (cons "allan" (cons 1000 empty)) 
      (cons (cons "barb" (cons 2000 empty))  
            (cons (cons "carl" (cons 1500 empty)) 
                  (cons (cons "dawn" (cons 3000 empty)) 
                   empty  ))))
