Rearrange the following lines to design a recursive helper method to solve this problem. Not all lines are useful. How to use this tool v Unused if (start == a.length) { return a[start]; } return a[start] + sumHelper (a, start 1); - if (a.length == e) { return 0; } if (a.length == 0) { return -1; } return a[start] + sumHelper (a, start + 1); Check Find Sum.java import java.util.Scanner; public class FindSum { EzyBooks catalog Help/FAQ public static int sum(int[] a) { return sumHelper (a, 0); if (start Load default template... } public static int sumHelper (int[] a, int start) { == a.length - 1) { return a[start]; } } public static void main (String [] args) { Scanner
