Что в итоге должен вернуть getNumbers?

public class Solution {
    public static long[] getNumbers(long N) {
        long start=System.currentTimeMillis();
        StringBuffer stringBuffer= new StringBuffer(Long.toString(N));
        ArrayList<Integer> list = new ArrayList();
        long[] result = new long [stringBuffer.length()];
        for (int i = 0; i < stringBuffer.length(); i++) {
            list.add(Integer.parseInt(String.valueOf(stringBuffer.charAt(i))));
        }
        int b=0;
        Collections.sort(list);
        for (Integer l: list) {
            result[b]= (long) Math.pow(l,stringBuffer.length());
            System.out.println(result[b]);
            b++;
        }
        System.out.println("Размер массива="+stringBuffer.length());
        long end=System.currentTimeMillis();
        System.out.println("Время "+(end - start)+" ms");
        System.out.println("memory: " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory())/(1024*1024) + " MB");
        return result;
    }

    public static void main(String[] args) {
        getNumbers(32);
    }
}
