Today is practice day, more than nine came to the classroom, sunshine, or mood, my Mac notebook has a kind of excitement.I looked at the basics in the morning, and the notes were re-organized once again. I closed the cloud notes I have learned the code to knock myself again, although very basic things but found that if you do not knock a few times it is easy to forgetLet's organize the code and comments for

/*Basic Practice Rectangle Area intersection Problem The description plane has two rectangles, their edges parallel to the x-axis or y-axis of the Cartesian coordinate system. For each rectangle, we give the coordinates of its pair of relative vertices, so you can programmatically figure out the intersection area of two rectangles. 　　Input format input contains only two lines, and each line describes a re

Basic Practice Special Palindrome numberTime limit: 1.0s memory Limit: 512.0MB problem description 123321 is a very special number, it reads from the left and reads from the right is the same.Enter a positive integer n, programming all such five-bit and six-bit decimal numbers to satisfy the sum of the numbers equal to N. Enter a line in the format that contains a positive integer n. The output format outpu

Basic practice hex to octal time limit: 1.0s memory limit: 512.0MBThe problem describes the given n hexadecimal positive integers, outputting their corresponding octal numbers. Enter the first behavior of the input format as a positive integer n (1Next n rows, each line a string of 0~9, uppercase letters A~F, representing the hexadecimal positive integer to be converted, each hexadecimal number is not more

Basic Practice Sequence SequencingTime limit: 1.0s memory limit: 512.0MB The problem description is given a sequence of length n, which arranges the sequence in small to large order. 1The second row contains n integers, and the absolute value of each integer is less than 10000 for the number to be sorted. Output format output one line, the sorted sequence is output in order from small to large. Sample Input

over, in order to deepen understanding and memoryIf you have a foundation, you can choose chapters to learn according to your needs.2.3. Instructor Recommendations1. Be sure to follow the course to practice, think more, and work more together on the scene.2. It is a very good learning habit to watch videos and make some records and notes on the side.3. Be sure not to rely too much on video, to learn to read the API and use Baidu, learn to think, lear

Ext JS 4 from the bottom of the class system has been reconstructed, this is the first time in the history of Ext JS to the class system of huge reconstruction. The new architecture is almost always applied to each of the Ext JS 4 classes, so it is important that you have a good understanding of it before you start coding. This manual applies to any developer who wants to create a new class or inherits existing classes in Ext JS 4, divided into 4 parts: Part One: "Overview"--explains the need to

[Java concurrent programming practice] ----- basic thread concepts, java ----- I have been learning Java concurrency for more than a month. I feel that I will forget some things after I have learned it for a while. I have made some notes but not the system. For a "system" with such a large Java concurrency ", you need to summarize and organize it to conquer it. I hope my colleagues can learn Java concurrent
