### Question:
RadixSort { public static String[] sort(String[] asciis) { String[] sorted = new String[asciis.length]; System.arraycopy(asciis, 0, sorted, 0, asciis.length); int max = 0; for (String asc : asciis) { max = max > asc.length() ? max : asc.length(); } int index = 0; while (index < max) { sorted = sortHelperLSD(sorted, index); index += 1; } return sorted; }  static String[] sort(String[] asciis); static void main(String[] args);  }### Answer:
@Test public void LSDSortTest() { String[] testArr1 = {"alatn", "hello", "succe", "donld", "hcdlo","heleh", "12321", "!*^&!"}; String[] result1 = RadixSort.sort(testArr1); System.out.println(Arrays.toString(result1)); String[] expected1 = {"alatn", "hello", "succe", "donld", "hcdlo","heleh", "12321", "!*^&!"}; assertArrayEquals(testArr1, expected1); }
