LeetCode No.237 Delete Node in a Linked List | #Linked-list

Q:

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.

A：

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

就是个很基础的概念：

temp.setNext(temp.getNext().getNext())
