Consider the code for the recursive method mystery shown in this code snippet: public static int mystery(int n) { if (n == 0) { return 0; } else { return (n + mystery(n-1)); } } What will be printed by the statement System.out.println(mystery(-4));?

Consider the helper method reversePrint, which uses recursion to display in reverse the elements in a section of an array limited by the firstIndex and lastIndex arguments. What statement should be used to complete the recursive method? public static void reversePrint(int[] array, int firstIndex, int lastIndex) { if (firstIndex < lastIndex) { ________________________________________ } System.out.println(array[firstIndex]); } public static void main(String[] args) { int [] numbers = { 4, 7, 1, 0, 2, 7 }; reversePrint(numbers, 0, numbers.length - 1); }
