LeetCode 237. Delete Node in a Linked List
Write a function to delete a node in a singly-linked list. You will not be given access to the head of the list, instead you will be given access to the node to be deleted directly.
It is guaranteed that the node to be deleted is not a tail node in the list.
Example 1:
Input: head = [4,5,1,9], node = 5
Output: [4,1,9]
Explanation: You are given the second node with value 5, the linked list should become 4 -> 1 -> 9 after calling your function.
method
void deleteNode(ListNode* node) {
node->val = node->next->val; // 把自己赋值为下一个节点
node->next = node->next->next; // 删除下一个节点
}
