如何使用两个指针指向的变量删除？

#include <iostream>

struct Node {
    int data;
    Node* next;
};

void deleteNode(Node** head, int value) {
    Node* current = *head;
    Node* previous = nullptr;

    // 遍历链表，直到找到要删除的节点
    while (current != nullptr && current->data != value) {
        previous = current;
        current = current->next;
    }

    // 如果找到了要删除的节点
    if (current != nullptr) {
        // 如果要删除的节点是头节点
        if (previous == nullptr) {
            *head = current->next;
        } else {
            previous->next = current->next;
        }

        // 释放要删除的节点的内存空间
        delete current;
    }
}

int main() {
    // 创建链表
    Node* head = new Node();
    Node* second = new Node();
    Node* third = new Node();

    head->data = 1;
    head->next = second;

    second->data = 2;
    second->next = third;

    third->data = 3;
    third->next = nullptr;

    // 删除节点
    deleteNode(&head, 2);

    // 打印链表
    Node* current = head;
    while (current != nullptr) {
        std::cout << current->data << " ";
        current = current->next;
    }

    return 0;
}
