Remove all elements from a linked list of integers that have valueval. Example Given:1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6,val= 6 Return:1 --> 2 --> 3 --> 4 --> 5 删除链表中所有值为val的节点。 /*** Definition for singly-linked list. * public class ListNode {...
在最后返回的时候,我们也是需要返回新节点的下一节点,也就是原来的head。 publicListNoderemoveElements2(ListNode head,intval){ListNode res=newListNode(0);res.next=head;ListNode pre=res;while(pre.next!=null){if(pre.next.val==val){pre.next=pre.next.next;}else{pre=pre.next;}if(pre==null)break...

六、HashMap、TreeMap、linkedHashMap区别? 七、HashMap和HashSet区别? 八、 HashMap的实现原理? 通过put和get存储和获取对象,存储对象时,我们将K/V传给put方法时,它调用hashcode计算hash从而得到bucket位置,进一步存储,HashMap会根据当前bucket的占用情况自动调整容量。获取对象时,我们将K传递给get,他调用hashcode计算...
Since element removal inside an ArrayList can induce a huge amount of array copying, the remove(int)-method is avoided. public static <T> void removeDuplicates(ArrayList<T> list) { int size = list.size(); int out = 0; { final Set<T> encountered = new HashSet<T>(); for (int in ...
add方法挺简单的,就是在链表尾部添加一个新的Node,也就是调用linkLast(e)方法。不过有一点要注意的是,当l==null, 也就是目前链表只有一个节点,所以first和last指向同一个节点。 get方法 public E get(int index) { checkElementIndex(index); return node(index).item; ...
