1、为什么不能用数组实现队列 因为用数组实现元素个数是固定的,不便于插入和删除。因此,用链表实现更合适。 2、链表结构 注意点: In a single linked list, the address of the first node is always stored in a reference node known as “front” (Some times it... ...
Map是 Key-Value键值对映射的抽象接口,该映射不包括重复的键,即一个键对应一个值。HashMap是Java Collection Framework的重要成员,也是Map族(如下图所示)中我们最为常用的一种。 简单地说,HashMap是基于哈希表的Map接口的实现,以Key-Value的形式存在,即存储的对象是 Node (同时包含了Key和Value) 。在HashMap中...
Linked List Cycle 题目链接 python代码实现: 实现思路: 快慢指针法。定义两个指针:快指针每次走一步;慢指针每次走两步。依次循环下去,如果链表存在环,那么快慢指针一定会有相等的时候。 为了便于理解,你可以想象在操场跑步的两个人,一个快一个慢,那么他们一定会相遇(无论他们的起始点是不是在操场)... ...
https://leetcode.com/problems/palindrome-linked-list/ Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 解题思路: CC150中的原题2.7。 有好几种解法。首先,如果题目不要求O(1)的空间的话。使用快慢指针,找到list的中点的...
This article will discuss the method of how to implement a function that deletes a given node in a linked list C++. Implement a Function to Delete a Given Node in a Linked List In this article, we implement a singly linked list from scratch without utilizing the containers from STL. Thus...

JAVA中HashSet、TreeSet和LinkedHashSet的比较,写在前面:嘤...嘤嘤,本菜鸡只会用C++的STL,通过前面的博文也可以看出来。
