Complete the following code snippet, which is intended to be a recursive method that will find the sum of all elements in an array of double values from the beginning of the array to index: // return the sum of all elements in arr[] public static double findSum(double arr[], int index) { if (index == 0) { _____________________ } else { return (arr[index] + findSum(arr, index – 1)); } } Assume that this method would be called using an existing array named myArray as follows: findSum(myArray,myArray.length – 1);
