In a singly linked list each node in the list stores the contents of the node and a reference (or pointer in some languages) to the next node in the list. It is one of the simplest way to store a collection of items. In this lesson we cover how to cr…

Reverse a singly linked list. Hint: A linked list can be reversed either iteratively or recursively. Could you implement both? 递归的办法: /** * Definition for singly-linked list. * public class ListNode { * int val; * ListNode next; * ListNode(int x) { v…

Implement an algorithm to delete a node in the middle of a singly linked list, given only access to that node. Have you met this question in a real interview?     Example Given 1->2->3->4, and node 3. return 1->2->4 LeetCode上的原题,请参见我之前的博客De…

Reverse a singly linked list. /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solution { public: ListNode* reverseList(ListNode* head) { if (head == NUL…

Problem: Implement a function to check if a singly linked list is a palindrome. 思路: 最简单的方法是 Reverse and compare. 另外一种非常经典的办法是用 Recursive 的思路,把一个list看成这种形式: 0 ( 1 ( 2 ( 3 ) 2 ) 1 ) 0 0 ( 1 ( 2 ( 3 3 ) 2 ) 1 ) 0 CC150里面给出的Code,非常简洁,贴在下面: length == 1 对应…

Given a linked list, remove the nth node from the end of list and return its head. For example, Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5. Note:Given n…

项目用到,实现一个recyclerView列表的item翻转动效,翻转的同时会将指定item置顶. (比如交换AB位置,A在0位置,指定的item B 在 i 位置) 原始使用的是插入B到0位置,然后移除B dataList.add(, bean);mAdapter.notifyItemInserted(0);mAdapter.notifyItemRangeChanged(0, dataList.size());dataList.remove(bean);mAdapter.notifyItemR…
