Question

A) For the Mark-and-Compact algorithm, what objects remain on the heap after collection?
Do each object stay in the same location after collection?

B)

Consider algorithms Mark-and-Sweep, Mark-and-Compact, Stop-and-Copy, and assume
that:

• Reachability analysis uses depth-first search, prioritizing lower addresses, and will skip
objects that have already been visited.
• Search starts from p, and then q.
• When the entire heap is traversed, objects are visited from left to right. You don’t need
to write down the newly created object copies, if any.

For each algorithm, write down the objects being visited during the garbage collection in
sequence. Mark which phase (e.g., mark, sweep, etc.) the object is visited in, if there are
multiple phases in an algorithm.
