Consider the following methods:

public static double average(int[] nums) { 

int sum = 0; for (int i = 0; i < nums.length; i++)

{

sum += nums[i]; }

return sum / nums.length;

} //average

public static int[] mystery(String[] a) { 

int[] temp = new int[a.length]; for (int i = 0; i < a.length; i++) {

temp[i] = a[i].length(); }

 return temp; } //mystery 

What is output by running the following?

String[] spelling = {"orange", "green", "red", "blue", "yellow"}; System.out.println(average(mystery(spelling)));
