Question

Consider the Mark-and-Sweep algorithm. What objects remain on the heap after collection? Consider algorithms Mark-and-Sweep, Mark-and-Compact, Stop-and-Copy. For each of them, write down the objects being visited during the collection in sequence. Assume 1) reachability analysis uses depth-first search, which will skip objects that have already been visited, 2) search starts from p, and then q, 3) 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.

Explanation / Answer

(a)

Solution:

From the Mark and Compact

(b)

(1)
