RecursiveCallbackFilterIterator
RecursiveCallb is a programming concept that describes a function calling itself as part of its execution. This self-referential nature is a fundamental aspect of recursion, a powerful problem-solving technique used in computer science. When a function makes a recursive call, it essentially creates a new instance of itself with modified parameters, working towards a base case. The base case is a condition within the recursive function that, when met, stops the recursion and prevents an infinite loop. Without a base case, a recursive function would continue to call itself indefinitely, leading to a stack overflow error.
The execution of recursive functions can be visualized as a stack of function calls. Each recursive call
