1. StructureList uses a double linked list (a doubly linked list) to manage elements.2. List abilityThe internal structure of the list is very different from the vector or deque, so it differs from them:The list does not support random access, it

The container is the place where the data is stored.The STL (Template Library) for C + + has two types of containers: sequential containers and associative containers. Simply put, a sequential container aggregates a single type of element into a

1. Ordinary single-linked list2. Kernel link ListI was stolen from other blogs, almost fooled past.I use keynote to draw it myself (alas!!) Drawing really is to let the human heart is very tired ah!! ）。The difference is not very obvious ah?!Read the

Recently looking at Leveldb source code, which used the LRU (Least recently used) cache, so do it yourself to achieve it. The LRU cache is typically implemented as a hash Map + Double Linked List, and I use std::map instead of a hash table.The

Exploitation of Linux heap overflow exploits unlinkTake a bit @ Ali Poly Security0 PrefaceBefore we learned more about the operating mechanism of GLIBC malloc (see article link for the end ), Let's start with a real heap overflow exploit. To tell

What isEpollWhat is Epoll? According to the man manual, it is an improved poll for handling large batches of handles . Of course, this is not the 2.6 kernel, it is introduced in the 2.5.44 kernel (Epoll (4) is a new API introduced in Linux kernel 2.5

ProblemDesign and implement a data structure for Least recently Used (LRU) cache. It should support the following operations:get and set.get(key)-Get The value ('ll always be positive) of the key if the key exists in the cache, otherwise

The initial purpose of college learning programming is directed at the game ~ but in just learning C language, completely unable to use the knowledge learned to make a playable game ╮ (╯_╰) ╭, after 1 years of learning is still the simplest greedy

ObjectiveWhy learn data structures and algorithms, if you learn to do Android, Javaweb, front-end, etc., are your martial arts cheats, but if your internal strength is not good enough, then the Kungfu is in vain.Data structures and algorithms: what

Objective:  to strengthen the understanding of the memory allocation of classes and objects, to strengthen the operation ability and to understand data structure. Structure:  The relationship between data elements. Data structures are:  with

What is a containerFirst, we have to understand what a container is, in C + +, where a container is defined as having an object type on the Datastore, which can hold other objects or pointers to other pairs of objects, which are called containers.

Data structure and algorithmic basics pointsLinked list1. A linked list is a linear set of data composed of nodes, each pointing to the next node through a pointer. It is a data structure that is composed of nodes and can be used to represent

Look at the concept is very hazy, there is no clear double-linked list exactly what needs to be done, in fact, for this structure should be able to write a lot of methods, and there is no specific criteria.But I really don't know how to do it. All

Title: Sort A linked list in O (n log n) time using constant space complexity.Train of thought: Require time complexity O (NLOGN)Knowledge Points: Merge sort, link list find Midpoint methodDisadvantages of existence: the boundary condition is more

1. PrefaceThis article mainly introduces the basic data types implemented by Linux kernel, including linked list, kernel object, kernel object reference count, kernel object collection,2. Linked list1. Basic structure of linked listThe kernel list

This article mainly introduces the PHP SPL standard database data structure stack (splstack) Introduction, stack (stack) is a special linear table, because it can only at one end of the linear table to insert or delete elements (that is, into the

Reprinted from: http://edsionte.com/techblog/archives/4019The partition page box allocator implemented in the Linux kernel based on the partner algorithm is suitable for large chunks of memory, and its allocated memory area is based on the page

The difference between a doubly linked list and a single-linked list is that he has one more domain to store the precursor nodes.Basic method implementation:New node:The next of the current node is the new node, and the new node's next is the

Two-way linked list is also called double linked list , which is a kind of linked list, and it has two pointers in each data node, pointing to direct successor and direct precursor respectively. Therefore, starting from any node in a two-way list,
