Linked list (linkedlist)
When an element needs to be able to be added at both ends of the list. Otherwise, use list
Resizable array list (list)
When the number of elements is not fixed and the subscript needs to be used.
Stack (stack)
When you need to implement LIFO (last on first out).
Queue (queue)
When you need to implement FIFO (first in first out).
Hash table (dictionary)
When you need to use key-value pairs (Key-value)
This article is mainly based on the "data Structure and algorithm analysis--c language description," a book of the contents of the list of chapters, the book author gives a list of ADT methods, but did not give all the methods of implementation. During the learning process, the code of Practice is recorded in the article, and some of the functions needed in the t

memory usage Efficiency: using simple key-value storage, memcached memory utilization is higher, and if Redis uses hash structure to do key-value storage, because of its combined compression, Its memory utilization is higher than memcached. Of course, this is related to your application scenario and data characteristics.

The framework is a set of articles such as the eight-unit document method. it exists to facilitate the talent to quickly write articles that conform to the rules.
A database is a document, which can save a lot of effort for reference during writing.
Architecture is the chapter method of writing books. this technology is useful when a large number of articles (not necessarily

Stack as one of the most commonly used data structures, has always been the most basic content of the algorithm contest, but it is a beginner's nightmare with recursion, I am here to review knowledge plus the benefit of the original intention of the new, write an article on the basis of the stack of detailed.Stack is also called LIFO table, the LIFO table, in fact, can be imagined as a stack of books, first

Programmers must not only cultivate their own technologies, but also cultivate their own character. Doesn't it mean that most problems in programming are character problems? Of course, this is about the cultivation of the programmer's character and personality.

because when the type of the key is a string type, the length property has no effect ....The use of dictionaries most of the time we care about the key to get the value, do not care about the order of the keys, but in order to better display the phone book we said earlier, you can sort the key (name) in the phone book.It's common in JavaScript to sort an array, and then you'll see silently, using the sort () of arrays. The main reason is that we usua
To make it easier for computers to serve us, we need to digitize all things in reality and store them in the computer, because there is a certain relationship between things in reality and things, so we need to study these relationships (forms of existence in the computer world and forms of existence in the real age ), that is to say, we need to study the logical structure in the data structure (several ways in which relations exist in the real world)
Time Test
This book uses a practical method to analyze the data structures and algorithms to be studied. We prefer to use a simple benchmarking method instead of Big O analysis. This test tells us how many seconds (or other time units) it takes to run a code segment. Our benchmark test time test measures the time it takes to run an algorithm. Benchmarking is a sc
