解法二(Java) /*** Definition for singly-linked list. * public class ListNode { * int val; * ListNode next; * ListNode(int x) { val = x; } * }*/classSolution {publicListNode reverseList(ListNode head) {if(head ==n
此解法与第四种解法思路类似,只不过是将栈换成了数组,然后新建node节点,以数组最后一位元素作为节点值,然后开始循环处理每个新的节点。 publicListNodereverseList5(ListNode head){if(head ==null|| head.next ==null) {returnhead; } ArrayList<Integer> list =newArrayList<Integer>();while(head !=null) { ...
Reverse Linked List II Reverse a linked list from position m to n. Do it in-place and in one-pass. For example: Given 1->2->3->4->5->NULL, m = 2 and n = 4, return1->4->3->2->5->NULL. Note: Given m, n satisfy the following condition: 1 ≤ m ≤ n ≤ length of ...
上面网页进行了解析,没怎么理解,有空下次继续。。。 Java 直接上面第一个代码的思路就可以,不会有最后有null问题 public class Solution { public ListNode ReverseList(ListNode head) { if(head==null) return null; //head为当前节点,如果当前节点为空的话,那就什么也不做,直接返回null; ListNode pre = nul...

java的reverse方法 在Java编程中，`reverse`方法可是一个非常实用且有趣的存在！它主要用于对各种数据结构中的元素顺序进行反转操作。下面就来详细地讲解一下这个方法。一、`StringBuilder`类中的`reverse`方法。1. 方法定义。`StringBuilder`类是可变字符序列，它提供了`reverse`方法来反转字符序列。其方法定义如下：pub...
反转从位置 m 到 n 的链表。请使用一趟扫描完成反转。 说明: 1 ≤ m ≤ n ≤ 链表长度。 示例: 输入: 1->2->3->4->5->NULL, m = 2, ...
