C and C++ do not have an automatic one built into the language, but Java does.
Cheney's algorithm, an extension of the semispace method, is one way to implement this procedure, and involves dividing the heap in half and copying elements back and forth between to-spaces. It's not recursion, but LISP was an early language to support it, and cycles tend to lead to problems in a similar process to this called Reference Counting. One implementation of this process involves putting a tag on every reachable block in memory and then freeing any block without a tag, and is known as Mark and Sweep. C and C++ do not have an automatic one built into the language, but Java does. FTP, identify this process where memory blocks no longer used are automatically trashed.
