AnswersEliminate all ‘b’ and ‘ac’ in an array of characters, you have to replace them in-place, and you are only allowed to iterate over the char array once.

Hi guys,
why over complicating it so much. The op just asks for flattening a list of lists of integers and implementing next and hasNext. No need for implementing Iterator thus far. Just forward requests to a backing list that just encapsulates the list of lists.
public class FlattenList {
int index = 0;
List<Integer> flattenedList = new ArrayList<>();
private FlattenList(){
}
public static FlattenList getList(List<List<Integer>> lists){
FlattenList flattenList = new FlattenList();
flattenList.flatten(lists);
return flattenList;
}
private void flatten(List<List<Integer>> lists) {
for(List<Integer> list : lists){
flattenedList.addAll(list);
}
}
public boolean hasNext(){
return flattenedList.size() > index;
}
public Integer next(){
Integer result = flattenedList.get(index);
index++;
return result;
}
}
and the test should look like this
public class FlattenListTest {
@Before
public void setUp() throws Exception {
}
@Test
public void test() {
FlattenList flattenList = FlattenList.getList(Arrays.asList(
Arrays.asList(6, 8),
Arrays.asList(4)
));
assertEquals(new Integer(6), flattenList.next());
assertEquals(new Integer(8), flattenList.next());
assertEquals(new Integer(4), flattenList.next());
assertEquals(false, flattenList.hasNext());
}
}
