Source: http://www.cnblogs.com/yangecnu/p/Introduction-Stack-and-Queue.html1.Basic ConceptsThe concept is simple, the stack is a OFF,LIFO data structure, and the queue is a first-in, fisrt (OUT,FIFO) structure, such as:2.ImplementNow see how to implement the above two data structures. Before doing so, the Framework design guidelines This book tells us that when d

In fact, all data structures are "graphs". A graph is actually a collection of vertices and edges. If the edge has a directivity is called a directed graph, otherwise it is a graph, edge can also have the right value. A graph with a path connection between any two points is called a connected graph, and the number of edges connected by vertices is called the degree of the vertex.Connected graphs without loo

This article first introduces some basic concepts about trees.Common arrays, lists, stacks, and queues are linear structures that are slow to access when storing large amounts of data, while trees are a nonlinear structure that reduces access time complexity to O (Logn).A structure similar to a tree in life is a genealogy. Each family had an ancestor, and the ancestors had several children, and each child c

data structures that can be persistedTitle Link: http://acm.xidian.edu.cn/problem.php?id=1181Using vectors to achieve persistenceThis requires a persistent data structure that supports interval queries. Here, using the vector cleverly implements the:pairThe code is as follows:1#include 2#include 3#include 4#include 5 #defineX First6 #defineY Second7 #defineN 1000

1./proc DirectoryThe Linux kernel provides a mechanism for accessing kernel internal data structures and changing kernel settings at run time through the/proc file system. The proc file system is a pseudo-file system that only exists in memory and does not occupy external memory space. It provides an interface for accessing system kernel data in a file system man

Several data structures in the python collection module (Counter, OrderedDict, namedtup) The collection module has several data structures that we may use. Counter is a sub-class of the dictionary and is responsible for counting a dictionary. It supports + addition, subtraction, and common elements. | calculates the Un
