iterated()

Create a function that applies func n times to a value.

Implementation

Args: func: The function to iterate Returns: A function that takes (value, n) and applies func n times

Example

                            double = lambda x: x * 2
repeated_double = iterated(double)
repeated_double(2, 3)  # 2 -> 4 -> 8 -> 16
                        

Expected output: 16
