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 -> 4after calling your function.

 

public class Solution {

    public void deleteNode(ListNode node) {

        node.val = node.next.val;

        node.next = node.next.next;

    }

}
