Problem:

Question: Part 1- Draw the Scheme node representation of list2.

What are the values of the following Scheme expressions?

Part 2- (cons ‘e ( cdr ( car lst2)))

Part 3- (append ( car lst2) ( car ( cdr lst2)))

Part 4- Assuming that list2 is still ‘((ab)(cd)). Write a Scheme expression that returns a list containing the first element of each of the lists in lst2. It should work on any list with the same structure as lst2. In the case of our lst2 it should return ‘(ac).

Please show all the calculations step by step.
