A linked list is a common and important data structure that dynamically allocates memory.When using arrays to store data, you must define a fixed length (that is, the number of elements) in advance. However, if it is difficult to determine the number of elements in advance, you must define an array large enough, to ensure success.Undoubtedly, this will cause a waste of memory. However, the
1. ConceptThe previous blog post we talked about the list, where a method remove () is a temporary comment, this method is a bit complicated, you need to add a previous () method to find the element to delete the previous node, this blog post we analyze the Remove () method.When you delete a node from a linked list, you need to find the node in front of the node

Topic:Given A linked list, determine if it has a cycle in it.Ideas:For judging whether the chain list has a ring, the method is very simple, with two pointers, beginning to point to the head node, one is a fast pointer, two steps at a time, a slow pointer, one step at a time, when two pointers coincide with the existence of the ring.Fast first into the ring, afte
The Code is a non-cyclic two-way linked list, including node insertion and deletion operations [cpp] // LinkList_D.cpp: Defines the entry point for the console application. // # include "stdafx. h "# include" stdio. h "# include" stdlib. h "# include" iostream "using namespace std; typedef int DataType; typedef struct DLNode {DataType data; struct DLNode * prior; struct DLNode * next;} DLNode, * DLinkList;
Topic:Reverse a linked list from position m to N. Do it in-place and in One-pass.For example:Given 1->2->3->4->5->NULL , m = 2 and n = 4,Return 1->4->3->2->5->NULL .Note:Given m, n satisfy the following condition:1 ≤ m ≤ n ≤length of list.Ideas:Find the M node, reverse the pointer from node m to N, and then concatenate the flip-up/** Definition for singly-linked
1. Node
The storage unit used to store a single data in the linked list.
A linked list must be composed of at least two parts: the data domain and the pointer domain. Generally, nodes are defined:
Struct Node
{
ELEM data; // The ELEM type refers to the basic data type.
Struct node * next;
}
Typedef struct node elemsn;

Reverse a linked list from position m to N. Do it in-place and in One-pass.For example:Given 1->2->3->4->5->NULL , m = 2 and n = 4,Return 1->4->3->2->5->NULL .Note:Given m, n satisfy the following condition:1 ≤ m ≤ n ≤length of list.It is strange why there is not one of the inverted list, it comes to this inverted list
The difference between a static list and a dynamic list:
Static linked lists and dynamic lists are two different representations of the linear chain-type storage structure.
1. Static linked lists are implemented in an array-like manner, are sequential storage structures, are contiguous on physical addresses, and need t
Given a singly linked list, return a random node ' s value from the linked list. Each node must has the same probability of being chosen.Follow up:What if the linked list was extremely large and its length is unknown? Could solve
Topic:Two functions are implemented, one can delete the second-to-last K-node in a single-linked list, and the other can delete the reciprocal K-node in a doubly-linked list.Requirements:If the list length is n, the time complexity reaches O (n), and the additional space complexity reaches O (1).Answer:Let the

Linked List cycle
Given a linked list, determine if it has a cycle in it. Follow up: Can you solve it without using extra space?
The question is to use the space of O (1) to determine whether a linked list has a ring. In my first
