Write a recursive method that takes a positive integer n and computes the sum of the first n positive integers. For example, if n is 5, the method should return 15, which is the sum of 1 + 2 + 3 + 4 + 5.

Your method should have the following signature:

public static int sum(int n)

Your solution should use recursion.
