Given a string and an int n, return a string made of the first n characters of the string, followed by the first n-1 characters of the string, and so on. You may assume that n is between 0 and the length of the string, inclusive (i.e. n >= 0 and n <= str.length()).

This exercise was taken from [codingbat.com](https://codingbat.com/prob/p128796) and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java.
