Write a recursive function (string* str n) that takes two arguments: a string x and a non-negative integer n. The non-negative integers are defined inductively as:
::= 0 | + 1
string* returns a string consisting of n occurrences of str. For example:
> (string* "Eugene" 3) "EugeneEugeneEugene"
You will want to use Racket's string-append function. Remember that the base case when recurring on a non-negative integer is 0.
