A very loving question. I have previously done a string inversion question on hangdian, but the two questions are very different. That question of hangdian requires gets (),There are also a variety of non-expressed characters. But this question! Because there are only spaces and line breaks, it is equivalent to what is eaten during receiving and what is spit out during output, in addition, the number of input cases can be used t
Inversion of control (IOC) is an important Object-Oriented Programming Law to reduce the coupling problem of computer programs. Another name is dependency injection ). DI for short.
IOC and Di are both design patterns. To understand them, you must first understand them. The general understanding can be: the IOC model is the sublimation of the factory model, and the IOC can be seen as a large factory, however, all the objects to be generated in this large factory are defined in the XML file, and
Digit inversion
Time Limit: 1 s memory limit: 128 MB[Problem description]Given an integer, please reverse the numbers on each digit to get a new number. The new number must also satisfy the common integer form.That is, unless the given original number is zero, the highest digit of the new number obtained after the inversion should not be zero (see example 2 ).[Input]The input file name is reverse. In.Input a total of 1 rows, an integer n.[Output]The output file name is reverse. Out.The output co
and T are the same length.2. For any two positions I and J, if Si and SJ are the same, then Ti and TJ are the same; if Si and SJ are different, then ti and TJ are different. (Si means the character of the string s in the position I, the meaning of TI is the character of the string T in the first position) with the string "ABCA" similar to the strings have "ABCA", "Cdac", "Zetz" and so on, now give a string s, output a similar dictionary order the smallest string.Input: HelloWorld output: ABCCDE
file, this is a feasible way.Results:Because of the previous to PHP is also half-baked, so went a lot of detours, fortunately, the final configuration of the environment, go to the final solution. The individual is still very fortunate, with the help of the net, standing on the shoulders of giants.Postscript:Of course, the actual processing of friends in the project, not so smooth, the middle also encountered a picture format problem, is the beginning of the EXIF only support JPEG and TIFF form

The interpretation of the IOC was: "Inversion of control are a common characteristic of frameworks, so saying this, lightweight containers are s Pecial because they use inversion the control are like saying the My car is special because it has wheels. "
I would like to perform a personal elaboration of this concept to facilitate my understanding. Control reversal, from the literal point of view, is the control power from passive to active and passive
Maybe some students do not understand, why should the picture reversal (not rotating OH), we are in the game development, in order to save the picture resources (space) may use to the picture inversion, for example, a character picture, facing the left, or right, if can not realize the picture inversion case, will need two pictures, the nonsense says less, See the effect on the code:
In the figure above, the actual two characters are using a pictur

method and strategy. And encapsulation change is an important means to achieve this principle, and will often change the state of packaging into a class.
3. The principle of reliance reversal (dependence inversion principle)Relying on the inverted principle, the high-level module should not rely on low-level modules, two should rely on abstraction, abstraction should not rely on details, the details should rely on abstraction. The plain thing is to p
Contact with these two concepts is often confused in the head, and a lot of information is not clear, even confused. After learning spring, we found that these two concepts are different periods of the spring core idea of the description, here is not much to say, there are many online data. It's always indefinitely to learn spring before you understand these two concepts, and finally get a thorough understanding today.
Simple:
IOC control reversal:
Topic:
Given A linked list, reverse the nodes of a linked list K at a time and return its modified list.
If the number of nodes is not a multiple of k then left-out nodes in the end should remain as it is.
You may not alter the values in the nodes, and only nodes itself is changed.
Only constant memory is allowed.
For example,Given this linked list:1->2->3->4->5
For k = 2, you should return:2->1->4->3->5
For k = 3, you should return:3->2->1->4->5 test instructions: Given a linked list and a num
This program implements PHP histogram//Its design idea is: first to use Imagecreate () to generate a blank shape, its program is implemented as follows://need two different colors, positive number of a negative one, an array of data, $path to save
In spring, the Dependency injection (DI) pattern implements the inversion of control (IoC) principle. Let's use an example to help understand dependency injection. Let's start with the Java version of the example, and then add spring functionality

Role: It guides us in how to properly resolve dependencies between modules, and it is also the core principle of framework design.
The essence of the dependency inversion principle is to require the relationship between classes to be based on an
