Webb8 apr. 2024 · I have the following recursive function below that returns the k to the s power of a certain integer. However I do not understand how it works. The base class is 1 when s becomes 0. How is it so that the returned value is actually k^s when 1 is returned? since 1 is returned I would expect powertoK (k, s) to be 1 all the time.
