SICP exercise 2.24

From Drewiki

Problem

Suppose we evaluate the expression (list 1 (list 2 (list 3 4))). Give the result printed by the interpreter, the corresponding box-and-pointer structure, and the interpretation of this as a tree (as in figure 2.6).

Solution

The result of evaluating the expression above in the interpreter is

(1 (2 (3 4)))

I'm too lazy to do the graphs for the other two parts.
