237. Delete Node in a Linked List【easy】

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.

解法一：

 /**

  * Definition for singly-linked list.

  * struct ListNode {

  *     int val;

  *     ListNode *next;

  *     ListNode(int x) : val(x), next(NULL) {}

  * };

  */

 class Solution {

 public:

     void deleteNode(ListNode* node) {

         node->val = node->next->val;

         ListNode * temp = node->next;

         node->next = temp->next;

         free(temp);

     }

 };
