给定一个访问节点的路径,写一个函数去删除在一个单向链表中除尾部以外的节点。
假设这个链表是1 -> 2 -> 3 -> 4,并且你被给予了第3个值为3的节点,那么在调用你的函数之后这个链表应该变为1 -> 2 -> 4。
原文
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.
代码
/**
* 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) {
if (node == NULL) {}
else {
ListNode* tmp = node->next;
node->val = tmp->val;
node->next = tmp->next;
delete tmp;
}
}
};
