1. 问题描述

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.

 7         }
 8         ListNode *pt = node;
 9         node->val = node->next->val;
10         node = node->next;
11         pt->next = node->next;
