每天一道LeetCode--237.Delete Node in a Linked List

Posted 2020-08-20 华裳绕指柔

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 -> 4after calling your function.

import cn.magicdu.extra.ListNode;

public class _237_Delete_Node_in_a_Linked_List {
    public void deleteNode(ListNode node) {
        node.val = node.next.val;
        node.next = node.next.next;
    }
}
