题目描述 给定一个链表,两两交换其中相邻的节点,并返回交换后的链表。 示例: 说明: 你的算法只能使用常数的额外空间。 你不能只是单纯的改变节点内部的值,而是需要实际的进行节点交换。 解题思路 利用递归的思想,依次交换 ...
Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists ...
We are given a linked list with head as the first node. Let's number the nodes in the list: node_1, node_2, node_3, ... etc. Each node may have ...
Given a non-empty, singly linked list with head node `head`, return a middle node of linked list. If there are two middle nodes, return the second ...
Given the head of a linked list, we repeatedly delete consecutive sequences of nodes that sum to 0 until there are no such sequences. After doing ...
题目描述: 给一个链表,两两交换其中的节点,然后返回交换后的链表。 您在真实的面试中是否遇到过这个题? Yes 样例 给出 1->2->3->4, 你应该返回的链表 ...
对于单链表而言,假设交换A、B两个节点,那么需要交换A与B的next指针以及A、B直接前驱的next指针。 需要注意特殊情况:1、当A与B相邻时:A->next = B;或者B->next = A; 2、当A和B元素相同时,则没有必要交换 ...
