Leet Code OJ 237. Delete Node in a Linked List [Difficulty: Easy]
题目:
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.
翻译:
写一个方法去删除单链表的一个节点(非尾节点),仅仅给出訪问这个节点的參数。
假定链表是1 -> 2 -> 3 -> 4,给你的节点是第三个节点(值为3),这个链表在调用你的方法后应该变为 1 -> 2 -> 4。
分析:
删除链表的节点的常规做法是改动上一个节点的next指针。然而这边并没有提供上一个节点的訪问方式。故转变思路改为删除下一节点。直接将下一个节点的val和next赋值给当前节点。
代码:
/**
* Definition for singly-linked list.
* public class ListNode {
* int val;
* ListNode next;
* ListNode(int x) { val = x; }
* }
*/
public class Solution {
public void deleteNode(ListNode node) {
node.val=node.next.val;
node.next=node.next.next;
}
}
