我们接下来要做的是,先把Mpre的next域指向NodeM节点的后一个节点; 再把NodeM所在节点移动到NodeN所在节点之后,使得NodeN的next域指向NodeM所在节点,NodeM所在节点next域指向NodeN的next域所指节点; 然后让NodeM指向Mpre的next域指向的节点; 演示图2 然后再重复上面的步骤; 这是NodeM和NodeN相遇,反转完成。 代码...

Loading...leetcode.com/problems/reverse-linked-list/ 题目很简单:输入一个单链表的头节点,返回反转后的链表的头节点。例如原始的链表是:1 -> 2 -> 3 -> 4 -> 5 -> null(或者None), 反转后的链表是: 5 -> 4 -> 3 -> 2 -> 1 -> null(或者None) ...
2 最后返回的是pre,不是cur recursive: https://leetcode.com/problems/reverse-linked-list/discuss/140916/Python-Iterative-and-Recursive recursive method 每次把head.next保存下来,这样就不用像我之前写的那样,用while循环去找最后一个node了,大大降低了时间复杂度 ...
