3.12 Draw box and pointer diagrams for the following Scheme lists: ((((a)))) (1 (2 (34)) (5)) ((a )) ((c) (d) b) e) Use the box and pointer diagrams of the last exercise to compute the following for each Scheme list for which they make sense: 3.13 (car (car )) (car (cdr L)) (car (cdr (cdr (cdr L)))) (cdr (car (cdr (cdr L)))) Represent the following elements as car/cdr expressions of the lists of Exercise 3.12: of the first list of the second list of the third list 3.14 For 3.14, the book missed part of the question. It should be a of the first list 3 of the second list c of the third list
