ListNode first=head; ListNode reverseHead=null;//建立一个新的节点用来存放结果while(first !=null) {//遍历输入链表,开始处理每一个节点ListNode second = first.next;//先处理第一个节点first,所以需要一个指针来存储first的后继first.next = reverseHead;//将first放到新链表头节点的头部reverseHead = first...

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 ...
reverseLinkedList(leftNode); // 第 5 步:接回到原来的链表中 pre.next = rightNode; leftNode.next = curr; return dummyNode.next; } private void reverseLinkedList(ListNode head) { // 也可以使用递归反转一个链表 ListNode pre = null; ListNode cur = head; while (cur != null) { ListNode nex...

Reverse a singly linked list. click to show more hints. Hint: A linked list can be reversed either iteratively or recursively. Could you implement both? 既然问了能否iteratively or recursively, 那就both把. iterative 解法: 总结就是得到下一个节点,更改当前节点指向,将指针往下移动,直到过完整个linked...
In this tutorial, we implemented two algorithms to reverse a linked list. As always, the source code for the article is available over on GitHub.Baeldung Pro comes with both absolutely No-Ads as well as finally with Dark Mode, for a clean learning experience: >> Explore a clean Baeldung...
