Given the two files a and B, each of them stores 5 billion URLs. Each url occupies 64 bytes and the memory limit is 4 GB. How can we find the common URLs of files a and B ?, 5 billion 4g It can be estimated that the size of each file is 5G * 64 = 300G, much larger than 4G. Therefore, it is impossible to fully load it into the memory for processing. Consider a divide-and-conquer approach.Traverse file a, ob

Java class and object 5, Java Class Object 5 Write a Java application, which includes two classes: Print class and main Class E. The output () function of a method in the Print class is to output 100 ~ All the daffodils between 999 (the cubes of each number are equal to the three numbers themselves, for example: 371 = 33 + 73 + 13 .) Test the Print class in the main method of main Class E. 1 class sXia

Java 5 Application of the original sub-operation class, Java 5 atomic type The java. util. concurrent. atomic package provides operations for basic data types, basic data types in arrays, and basic data types in classes. For more information, see API. The following example briefly introduces the use of the AtomicInteger class: 1 public class AtomicTest { 2 public static void main(String[] args) { 3

Section 5 clone [5] The object model in PHP5 calls an object through reference, but sometimes you may want to create a copy of the object and expect that the change of the original object will not affect the copy. for this purpose, PHP defines a special method called _ clone. like _ construct and _ destruct, the front has two underscores. By default, the _ clone method is used to create an object with the

5.html 5 path Representation The role of paths in html is to introduce external resources, such as css files, js files, and media files. The paths are divided into relative paths and absolute paths. The relative path is another page path relative to the link page. The absolute path is the complete Path Directly starting from file: // disk operator.

1.ScrollView, which inherits from Framelayout, so it is a special type of framelayout,Because it can use the user scroll to display a list of views that occupy more space than the physical display. It is important to note thatScrollView can contain only one child view or view group, and in the actual project, it usually contains a vertical linearlayout.It is important to note that ScrollView cannot be used with the ListView because the ListView has already processed the vertical direction of the

most programming work aims to make up for our limited intelligence. Programmers who are proficient in programming are modest people who know how limited their minds are. Those who have poor programming skills always refuse to accept the fact that they are not competent in their work, so that they cannot become good programmers. Admit that you have limited intelligence and learn to make up for it, you will become a better programmer. The more humble you are, the faster your progress will be.Many
