Though normally invoked automatically, some implementations permit the manual triggering of this, allowing a program to continue running in a resource- scarce environment.
It was invented by John McCarthy in 1959 to solve a problem he encountered in LISP. One potential drawback of this technique is that programs can pause unpredictably as this operation runs.  Though normally invoked automatically, some implementations permit the manual triggering of this, allowing a program to continue running in a resource- scarce environment. Mark and Sweep is a basic implementation strategy of, FTP, what prominent feature of programming languages such as Java and C#  [see-sharp] in which unused memory resource are reclaimed by the system?
