LeetCode：删除链表中的节点

Posted 2020-11-21 一路一沙

C++示例：

/**
 * 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 || node->next == NULL) {
            cout << "The node is empty or the node is the rear node." << endl;
            return;
        }
        ListNode* temp = node->next;
        node->val = temp->val;
        node->next = temp->next;
        delete temp;
    }
};
