Overview

Create a simple function decorator. Your decorator should calculate the execution time of that function that it decorates.

Requirements

We currently have a decorator function time_taken that will be used to decorate calculate_sqrt. The decorator function time_taken calculates the time taken by the decorated function to run, and the time library is used for this purpose.

Implement the decorator function under time_taken where the parameter func is the function that time_taken will be used to decorate.
Decorate calculate_sqrt using time_taken on line 13.
Remove line 24 once the decorator is applied on line 13.
