This recursive function is operating on the array data structure. The method is to find the sum of a given array of integers, recursively. You are to make simple public wrapper function that you pass the array into first, then call the recursive private helper method which takes in the array and an integer. Pseudo code is acceptable. An example is [3,5,1,7,9]; begin at index 4 and add the value 9 to the recursive call at index 3, and repeat. 01234 Below are the method headers and Javadocs: /** * Public method that returns the sum * @param arr an array of integers > 0 public int rsum(int[] arr) { /** *Helper method for rsum(int[]) @param arr an array of integers > 0 @param n an integer private int rsum(int arr, int n) {
