    Question: What is Garbage Collection? Answer: Garbage collection (GC) is a dynamic approach to automatic memory management and heap allocation that processes and identifies dead memory blocks and reallocates storage for reuse. Every garbage collector needs to begin collection by find- ing the root set — the live pointers on the runtime stack — in order to later find all reachable heap-allocated objects.
