Repeat Exercise 7.7.3 for the cases that o has

a) Only references from cars 22 and 31.


b) No references other than from car 11.

Exercise 7.7.3

Suppose the heap consists of exactly the nine cars on three trains shown in Fig. 7.30 (i.e., ignore the ellipses). Object o in car 11 has references from cars 12, 23, and 32. When we garbage collect car 11, where might o wind up?
