First, insert sort1, the idea: the principle is similar to grab the poker, inserts and finds in the orderly table, inserts the suitable position, after the element needs to move backwards2. Complexity of Time:Best: O (N), positive order case, only comparison time, no moving timeWorst: O (N2), reverse caseAverage: O (N2)3. Auxiliary space: O (1)4, Stability: stable5, suitable for occasions: suitable for the initial sequence of the basic order of the situation, or n small time, insert sorting effi

I/O operation is a very important operation in computer processing, how to achieve effective control of I/O device to better meet the user's input/output requirements, is one of the most important problems in equipment management. In the development of computer technology, I/O control mode is also constantly developing, the requirements of I/O control is mainly based on minimizing the interference of host to I/O control, freeing the host from the complex I/O control affairs to more complete its

Click the slider on the right side of the "direct access" and the Green Representative opens. 6. Check the options that require direct access, as an example of "accessibility

Question 1: When to use crossover and when to use Direct connect. Standard serial Port pin 2 is RX, pin 3 is TX, (that is, the nine-pin serial port 2nd PIN connection is the main control chip RXD pin, 3rd pin is connected to the main control chip TXD pin), if the SCM Development Board serial port and the computer serial port are standard serial port, the two serial ports should be connected with a crossover line. But in real life straight line most (

MinGW Introduction MINGW (minimalist GNU on Windows) is an emulated Linux compilation environment that compiles Linux programs under Windows, and provides Linux C, C + + header files, system libraries, and a collection of compilation tools under Linux, such as GCC , g++, and make tools. Allows the compiled binary to run on Win

Recently, we have done one thing: to port yaffs from Linux to the real address mode (yaffs direct). Since it is a real address, therefore, it can be directly used in a program that does not run the operating system, or an operating system that runs UCOS, nucleus, and other real addresses. This method is widely used to port yaffs to C51. In this way, yaffs is named yaffs dircet. In fact, this part of transplantation only needs to understand the basic f

ProblemHow can you define a route in a way that is closer to the resource (controller,action).Solution SolutionsYou can use attribute routing to declare routes directly at the resource level. Simply use the attribute route Routeattribute on the Action, and then pass a related route template to it. Attribute routing is essentially the same as a centralized route in the meaning of a route template, and all route parameters should use curly braces and match the Action used.

center, take a non-identical automorphism transform \ (\tau (a) =b\neq a\) and inner automorphism \ (\sigma_a\), thus having \ (\tau\sigma_a=\sigma_a\tau\), You can then prove that \ (a^{-1}b\) is the center of \ (g\). Thus if \ (\text{aut}\:g\) has a center, then \ (g\) also has the center. Conversely, if \ (g\) has no center, then \ (\text{aut}\:g\) has no center. Consider the following questions:　　? Proof \ (s_n\) and \ (\text{aut}\:s_n\) are no central groups;　　? The necessary and sufficien

Direct insertion Sorting algorithmBasic idea:The n order of the elements to be sorted as an ordered table and an unordered table, the beginning of the ordered table has only one element, the unordered table has n-1 elements; The sorting process takes the first element out of an unordered table, inserts it into an ordered table, makes it a new ordered table, and repeats the entire sort process n-1 times.　Instance:0. Initial state 3,1,5,7,2,4,9,6 (a tot

In the direct insertion sort, in Min's book it is necessary to set the Sentinel, the role of the Sentinel is to avoid the array out of bounds, so in the first position to set Sentinel, after thinking this algorithm for me the most worthy of learning is to compare the location of the move at the same time, this will reduce the complexity of timeData structure for#define MAXSIZE 20int KeyType;struct sqList{ KeyType r[MAXSIZE+1]; int length;};The c
