Box-and-pointer and memory-vector representations

Draw the box-and-pointer representation and the memory-vector representation (as in figure 5.14) of the list structure produced by

(define x (cons 1 2))

(define y (list x x))

with the free pointer initially p1 . What is the final value of free ? What pointers represent the values of x and y ?
