篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了[LeetCode] 237. Delete Node in a Linked List相关的知识,希望对你有一定的参考价值。
Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.
Supposed the linked list is 1 -> 2 -> 3 -> 4
and you are given the third node with value 3
, the linked list should become 1 -> 2 -> 4
after calling your function.
思路:这个题有点坑,常规思路的删除节点可以看203. Remove Linked List Elements。
这个题只告诉了你要删除的节点,没有告诉你删除节点的val.
1 public class Solution { 2 public void deleteNode(ListNode node) { 3 node.val = node.next.val; 4 node.next = node.next.next; 5 }
