C++中的嵌套链表和函数

#include <iostream>

class Node {
public:
    int data;
    Node* next;

    Node(int value) {
        data = value;
        next = nullptr;
    }
};

int main() {
    // 创建第一层链表
    Node* head1 = new Node(1);
    Node* node1 = new Node(2);
    Node* node2 = new Node(3);
    head1->next = node1;
    node1->next = node2;

    // 创建第二层链表
    Node* head2 = new Node(4);
    Node* node3 = new Node(5);
    head2->next = node3;

    // 将第二层链表作为第一层链表的一个节点
    node2->next = head2;

    // 遍历嵌套链表
    Node* current = head1;
    while (current != nullptr) {
        std::cout << current->data << " ";
        if (current->next != nullptr) {
            std::cout << "-> ";
        }
        current = current->next;
    }

    return 0;
}
