The article will not explain the contents of the

Sophomore semester, just after teaching C + + began to question what they have learned.We spent more than a year, learned C, learned C + +, learned the data structure but why I can do is only limited to brush OJ it? (Of course, OJ Brush is not much) is not as good as reading medium students can at least use flash to make a game out. Then accidentally saw the roommate's book, and had always heard that

senior Java programmers: They are proficient in this language and have the desire and the need to take full advantage of the new features that Java NIO offers when it comes to large-scale, complex data processing tasks. In the process of writing, it is assumed that you have a good understanding of JDK standard class packages, object-oriented design techniques, i

process statistics, analyze and visualize data. Through various examples, the reader can learn the core algorithm of machine learning, and can apply it to some strategic tasks, such as classification, prediction, recommendation. In addition, they can be used to implement some of the more advanced features, such as summarization and simplification. I've seen a part of this book before, but the internship in

tell readers the relationship between element objects and element operations, this even childhood Classic is also very likely to cause occasional nostalgia and resonance. When describing chained storage, I gave an example of hospital rankings, "As long as you pay attention to whether the previous number has been called or called, the next round will arrive." This is just a little bit of detail in your life. It is also the first time you can use this to describe the

main purpose is to separate the specific implementations of the abstract data types from their functions. The program must know what the operation is doing, but it's better if you don't know how to do it.tables, stacks, and queues may be three basic data structures in all computer science, and a large number of examples attest to their wide range of uses.
