Question: 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

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.
