Write a recursive method called writeNums that takes an integer n as a parameter and prints to the console the first n integers starting with 1 in sequential order, separated by commas. For example, consider the following calls:

writeNums(5); // would produce 1, 2, 3, 4, 5

writeNums(12); //would produce 1, 2, 3, 4, 5, 6, 7, 8, 8, 10, 11, 12
