以下是在Java中实现单向链表反转的两种常见方法: **一、迭代法** 1. **思路** - 需要三个指针,分别表示当前节点(`cur`)、当前节点的前驱节点(`pre`)和当前节点的后继节点(`next`)。 - 初始时,`pre`为`null`,`cur`指向链表的头节点。 - 在遍历链表的过程中,先保存`cur`的后继节点到`next`,然后将`cur`的`next`指针指向`pre`,接着更新`pre`为`cur`,`cur`为`next`,直到`cur`为`null`,此时`pre`就是反转后的链表头节点。 2. **示例代码** ```java class Node { public int value; public Node next; public Node(int i) { value = i; next = null; } // 向链表中添加新节点 public void add(Node head, Node add) { if (head == null) { return; } while (head.next!= null) { head = head.next; } head.next = add; } // 由头节点出发顺序遍历整个链表 public static void print(Node head) { if (head == null) { System.out.println("链表为空"); } while (head!= null) { System.out.print((head.value + " => ")); head = head.next; } } // 反转链表(迭代的方式顺序逐步处理) public static Node reverse(Node head) { if (head == null || head.next == null) { return head; } Node cur = head; Node pre = null; Node next = null; while (cur!= null) { next = cur.next; cur.next = pre; pre = cur; cur = next; } return pre; } } ``` **二、递归法** 1. **思路** - 对于递归反转链表,基本思想是将链表除了头节点之外的部分先递归反转,然后将头节点连接到反转后的链表后面。 - 递归的终止条件是当链表只有一个节点或者为空时,直接返回该节点。 2. **示例代码** ```java class Node { public int value; public Node next; public Node(int i) { value = i; next = null; } // 递归方法反转链表 public Node reverseRecurrence(Node head) { if (head.next == null) { return head; } Node last = reverseRecurrence(head.next); head.next.next = head; head.next = null; return last; } } ``` 点击前往免费阅读更多精彩小说

Nine-linked toy

The nine-ring chain was a traditional Chinese folk intelligence toy. It was made of nine rings made of metal wire, which were set on a horizontal plate or various frames, and were connected with a ring handle. The player could unlock the nine rings separately or combine them into one by repeating the operation according to a certain program. The nine-linked chain could be traced back to the Warring States Period. Xu Ke, who was at the end of the Qing Dynasty and the beginning of the Republic of China, recorded the solution to the nine-linked chain in detail in the book "Qing Bai Lei Banknote." The nine-linked chain was not only a child's toy, but also an educational tool that was beneficial to intellectual development. Through the process of solving puzzles, children need to use logical thinking to cultivate patience and perseverance. The nine linked chains were also challenging, regular, and interesting, attracting people's curiosity and desire to conquer. With the development of the times, the Nine Chain Rings had also evolved. The modern Nine Chain Rings not only retained the traditional metal rings, but also had various changes in materials and shapes. There was also an electronic version of the 9-chain game, which added a new element to the puzzle game.

Reversing the novel of socrates

The Reverse of Socrates was a collection of short stories by Japanese novelist Kotaro Ishizaka, published by Sichuan Literature and Art Press. There were a total of five short stories in the book, with the teenagers as the main characters, carrying out the theme of "love and peace" by Kotaro Izu. Kotaro Izaka was worried that the book would be regarded as children's literature, but although it was a story about boys and girls, it could make adults cry and think deeply about the theme conveyed in it. For example, in the short story "He's Not socrates"(which was also the origin of the title), it depicted the smart child Anzhai and the prejudiced Kurumi. Borrowing the famous quote of socrates,"I only know that I know nothing," the students designed a plan to let Kurumi put aside her prejudice and truly know others, thinking like socrates. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
