The first two articles describe two insertion sorting algorithms: Direct insert sort and hill sort. This article describes a sort of selection: direct selection of sorting. It can be seen from the name that the direct selection sort is similar to the direct insertion sort, where the same points are divided between the

Many people say that the use of reflection will have a performance problem, it will be more than the direct call how much slower, the following test. Call vs Reflection Call directly Here's a demo to verify the performance difference between the direct call and the reflection call, the code is as follows: 1 namespace ConsoleApplication7 2 {3 class program 4 {5 static void Main (string[] arg

A direct insert sort is the simplest sort of insertion .Insert Sort : Each trip adds a sorted record to the appropriate location of the ordered queue according to the size of its keyword, knowing that all insertions are complete.(1) We first treat the element labeled 0 in this sequence as an ordered sequence with a number of 1 elements.(2) Then we have to put R1, R2, ..., RN-1 into this ordered sequence in turn. So, we need an external loop that scans

There are many methods to introduce Javascript in Asp.net. I mainly talked about the following two types during my career as a cow.In my opinion, it can be divided into direct or indirect introduction.1. Direct Introduction. Call custom javascript Functions on the front-end page:1. Open the front-end page and add the script element between the head element and set the type element to "text/javascript ". The

Question 1: When to use crossover and when to use direct connection? The Standard Serial Port Pin 2 is RX, and Pin 3 is TX (that is, the 9-pin Serial Port 2 is connected to the rxd pin of the master chip, pin 3 is connected to the txd pin of the main control chip). If the serial port of the Single Chip Microcomputer Development Board and the serial port of the computer are both standard serial ports, the two serial ports should be connected using a cr

The basic idea of choosing a sort Each trip selects the smallest record of the keyword from the record to be sorted, placing the order at the end of the ordered sub-file, knowing that all records are sorted. There are two main options for sorting: Direct selection of sort (or simple selection sort) and heap sorting. Direct selection of the basic idea of sorting At the beginning o

-connected, the directory table should have the same capacity as the number of cached blocks.Example: a machine memory capacity of 1m,cache capacity of 32KB, the size of each block is 16 characters (or bytes). Outlines the main, cached address format, table of contents, and its capacity.　　　　Capacity: 211=2048 (or 32k/16=2048) is the same as the number of buffer blocks.advantages : High hit ratio, cache storage space utilization is high.　　disadvantage : When accessing related memory, it should be

Bubble sort (Bubble sort) basic idea: 22 Compare the keywords of adjacent records, if the reverse order is exchanged until there are no reversed records. The time complexity is O (N2).The basic idea of simple Selection sort is to select the smallest record of a keyword from a n-i+1 record and exchange it with the first record by comparing N-i keywords. It should be said that although the same as the bubble sort is O (N2), the simple selection of the sort performance is slightly better than the b

is the string that contains the body of the regular expression, the text that appears between the diagonal pairs in the direct amount of the regular expression that is described later. The second parameter is optional. If this parameter is provided, it shows the flag of the regular expression, which is described in the following log (please be concerned).Use the RegExp () constructor to create an example of a regular expression:Defines a global, nine

Direct Cable Connection is one of the most common LAN solutions for only two computers. Direct Cable Connection This method has a small investment, simple and practical features, it only needs a connecting line can be used on the computer and the mouth or serial port two computers connected to achieve resource sharing. So it is more suitable for the family to have two computers, especially the new one old t

I discussed with ZL earlier about using tcpmp to play videos in wince6.0. He believes that direct video writing should make video playing smoother. Today, I tested it on our platform and made benchmark using the following methods: GDI, direct, and DirectDraw. Direct is what he calls Direct Writing and video storage. T

Bytebuffer There are two kinds of heap bytebuffer, which are allocated in the JVM's heap memory and are directly responsible for garbage collection by the Java Virtual Machine, one of which is that the direct Bytebuffer is allocated via JNI in memory outside the virtual machine. The use of this fast memory cannot be viewed through jmap. It can only be viewed by top to see its memory usage.The JVM heap memory size can be set by-XMX, and the same

During the class loading process in the JVM, during the parsing phase, the Java virtual Opportunity replaces the symbolic reference in class two-level data with a direct reference. 1. Symbol reference (symbolic References):A symbol reference describes a target in a set of symbols, which can be any form of literal, as long as it can be used without ambiguity in the target. For example, in a Class file it appears as constants of type Constant_class_info

using PowerShell Directmanaging VMS from Hyper-V hostsWith PowerShell Direct, we don't have to worry about network or firewall restrictions because it works regardless of the network or remote management configuration. So, a lot of friends will ask, since it is not through the network and firewall that is how to connect it? In fact PowerShell's connection is via VMBus instead of through the network.Before PowerShell
