Represent the following elements as car/cdr expressions of the lists of the previous exercise.

1. a of the first list

2. 3 of the second list

Hint:

car = first item

cdr = second and all subsequent items in list

Example:

car( 2 3 4) = 2

car( (2) 3 4) = (2)

cdr( 2 3 4) = 3 4

cdr( (2) 3 4) = 3 4

cdr( (2) (3) (4) ) = (3) (4)
