linked list的基礎就是struct,所以先建立一個自訂的struct型別,因為linked list是靠struct串聯起來,所以最後要多一個struct pointer指向下一個struct。 25行 structlist*head=NULL; structlist*current=NULL; structlist*prev=NULL; 建立linked list最基本需要三個指標,head指向linked list的第一個struct,current指向目...
建立linked list最基本需要三個指標,head指向linked list的第一個struct,current指向目前剛建立的struct,prev則指向前一個struct,目的在指向下一個struct,對於未使用的pointer,一律指定為NULL,這是一個好的coding style,可以藉由判斷是否為NULL判斷此pointer是否被使用。 39行 current = (struct list *)malloc(sizeof(...
Palindrome Linked List 1,题目要求 Given a singly linked list, determine if it is a palindrome. 给出一个单链表,确定它是否是回文。 2,题目思路 对于这道题,是判断一个链表是否构成回文形式。 一般来说,判断一个字符串或者一个数组是不是回文比较简单,直接两端向中间依次进行比较即可,但是链表是个比较特殊...
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)... ...
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, we need to define some necessary functions to manage nodes in a linked list. The insertNode element is the core funct...
With MS c/c++ Compiler it is giving me runtime error!!! #include <iostream> #include <algorithm> #include <cmath> using namespace std; class List{ protected: struct node{ int info; struct node *next; }; typedef struct node *NODEPTR; ...

141. Linked List Cycle题目Given a linked list, determine if it has a cycle in it. Follow up: Can you solve it without using extra space? 解答/** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {}...
Using std::list Here’s how a programmer declares a linked list using STL (cribbed from the aforementioned article): struct person { unsigned age; unsigned weight; }; std::list <person*> people; After adding a few members to the linked list, we’d get something that looks like this in...
