About RedisRedis is one of the industry's leading key-value NoSQL databases. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash

XML Application--xml improved compression and transfer performance XML is a text markup format designed for clarity and ease of use, without regard for brevity. As with any design, XML has some weaknesses, one of which is the cost of translating

In php, we usually cannot get the desired result for floating-point computing. Why, next, we will analyze the problem and organize some useful examples for you. In php, we usually cannot get the desired result for floating-point computing. Why, next,

Common:I am always used to call the common law, because I really can not find a proper name to describe it, in fact, is the simplest way, a little program based on the people are able to think, that is the SHIFT + count, very simple, not much to say,

The integer type is 32-bit and has 4 bytes. Now we need to be able to extract one of its 32-bit values. But the smallest integer type of Delphi is also a byte (8 bits): byte (unsigned), struct int (Signed ). Otherwise, start with extracting a byte:

Topic:An integer is stored in memory and outputs the number of 1 in the binary representation of itIdeas:To determine the number of 1 in the binary representation of this integer, it is the topic of the [bitwise operation].The first thought of

Tree-like arrayTree-like array:is a novel design of the array structure, it can efficiently get the number of consecutive n in the array.Linear structures can only scan elements one by one, while a tree-like structure allows for a jump

Any number inside the computer is represented by a binary representation, which can be used to quickly determine the position of the lowest bit 1 in the binary representation of the n!.Solution One:Divides the binary number of a number by 2, and if

First, IntroductionRedis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash type). These data

There are many floating point number processing functions in php, including ceil, floor, round, and intval. After they are processed, they can return the expected floating point decimal places, next I will introduce some usage and Problem Analysis

If you use php +-*/to calculate the floating point number, you may encounter some calculation result errors, such as echo intval (0.58*100); 57 is printed instead of 58, this is actually a bug that the underlying binary of the computer cannot

Bit operation is a magical operation, can be very clever to solve some problems, at the same time the speed is very fast. The basic concepts of bit operations, as well as some common methods for bitwise operations, are described below. 1, the basic
