What are the advantages of the mark-and-sweep garbage collection algorithm?

The mark-and-sweep algorithm has several advantages, including efficient memory management and the ability to reclaim memory from cyclic references.

Can you explain how it works?

Sure! It works in two phases: first, it marks all reachable objects, and then it sweeps through memory to collect unmarked objects.

Are there any downsides to using it?

Yes, it can lead to pauses in program execution during the collection process, which may affect performance in real-time applications.

How does it compare to other garbage collection methods?

Compared to other methods like reference counting, mark-and-sweep can handle cyclic references better but may have longer pause times.

Is it suitable for all programming languages?

It's commonly used in languages like Java and Python, but its suitability depends on the specific requirements of the application.
