https://leetcode.com/problems/reverse-linked-list-ii/ 题意分析: 跟定一个链表,和位置m,n。将m到n的节点翻转。 题目思路: 和前面全部翻转的类似。 代码(Python): View Code 转载请注明出处:http://www.cnblogs.com/chruny/p/5088851.html
原题地址:https://oj.leetcode.com/problems/reverse-linked-list-ii/ 题意: Reverse a linked list from positionmton. Do it in-place and in one-pass. For example: Given1->2->3->4->5->NULL,m= 2 andn= 4, return1->4->3->2->5->NULL. Note: Givenm,nsatisfy the following conditi...

def reverseList2(self, head: ListNode) -> ListNode: """ 双指针法 :param head: :return: """ # 空表时直接返空 if head is None: return None # 初始化cur为head cur = head while head.next != None: # 当head的next非空时, 完成局部反转 ...
new_head = self.reverseList(head.next) head.next.next = head head.next = None return new_head 逻辑解释 递归终止条件:如果头节点head为空或者head.next为空(意味着链表为空或者只有一个元素),递归停止并返回当前的头节点。 递归调用:递归地调用reverseList来反转从第二个节点开始的链表。在递归返回的过程...
