Write a recursive function named starString that accepts an integer parameter n and returns a string of stars (asterisks) 2n long (i.e., 2 to the nth power). For example:

Call Returns Reason
starString(0); "*" 20 = 1
starString(1); "**" 21 = 2
starString(2); "****" 22 = 4
starString(3); "********" 23 = 8
starString(4); "****************" 24 = 16

You should throw an integer exception if passed a value less than 0.
