c++头插法反转链表

c 头插法反转链表是一种将链表进行倒置的方法。具体实现可以参考以下代码：

link *reverse(link *head) {
    link *new_head = NULL;
    link *temp = NULL;
    
    if (head == NULL || head->next == NULL) {
        return head;
    }
    
    while (head != NULL) {
        temp = head; //将 temp 从 head 中摘除
        head = head->next; //将 temp 插入到 new_head 的头部
        temp->next = new_head;
        new_head = temp;
    }
    
    return new_head;
}

这段代码使用了头插法的思路实现链表的反转。通过遍历原链表，每次将头部的节点摘下并插入到新链表的头部，最终得到了一个反转后的链表。你可以将原链表的头节点作为参数传入该函数，函数将返回反转后的链表的头节点。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
