237. Delete Node in a Linked List
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.
java实现--方法没有给出头结点,只能将本结点的下一结点的值赋值给该结点,然后删除下一结点
刚开始没想明白。。。
/** * 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) { if(node!=null){ node.val=node.next.val; node.next=node.next.next; } } }
