Once you have … WebHow Recursion Really Works This is how method calls (recursive and non-recursive) really work: At runtime, a stack of activation records(ARs) is maintained: one AR for each active method, where "active" means: has been called, This stack is also referred to as the call stack. Each AR includes space for: the method's parameters,

Meng, S. Arthur 8 WebThis information is called an activation record. Further subroutine calls add to the stack. Each return from a subroutine pops the top activation record off the stack. As an example, here is a recursive implementation for the factorial function.
