Write a recursive method called writeSquares that accepts an integer parameter and prints the first squares separated by commas, with the odd squares in descending order followed by the even squares in ascending order. For example, writeSquares(8); prints the following output:

49, 25, 9, 1, 4, 16, 36, 64

A call of writeSquares(1); prints 1. The method should throw an IllegalArgumentException if it is passed a value less than 1.
