A simple and pure PHP paging class His features: simple, accept parameters, and give pages; flexibility: you can decide the name of the top or Next page (for example, prev, nex t, and so on) you can determine the number of pages displayed on each page. a packaging method is provided to adapt to different webpage structures. for example, if a webpage contains (1 ...), And so on. note: There are two static methods in the demo code t

. Other classes can do things that can be done by defining the exception class. However, the exception class is always designed to be very simple, and they provide properties that can be easily extracted from error handling. When designing a module to handle multiple exceptions, it is often necessary to define a basic class, and other classes to deal with some special cases on this basis. class Error (Exception): "" "," "" "" "" "" " Pass Class Inputerror (Error): "" "Exception raised for

)) # Generator Expression In fact, writing a list resolution, at least on the basis of a function, is basically equivalent to including a generator expression in a list built-in call to force it to generate all the results in the list at once.>>> List (x * * 2 for X in range (4)) [0, 1, 4, 9]However, the generator expression is quite different from the execution process: instead of building the result in memory, it returns a generator object that will support the iterative protocol and operate i

pools ), your process holds shared pool latches for the entire dump duration so this shocould be used only as a last resort in busy production instances. dumping a big shared pool cocould hang your instance for quite some time. dumping private process heaps is safer as that way only the target process is affected. The heapdump output file structure is actually very simple, all you need to look at is the heap dump header to see in which heap the following chunks of memory belong (as there may be

Scapegoat Tree template question.We found that the primitive cannot compare size.Use the balance tree to assign a value to each formula to compare the size. Each node in the tree has a l,r value of l+r. The left node is l,mid and the right node is the same. So the allocation value can obviously compare size.But the balance tree cannot be rotated, so use the scapegoat tree.Siz to be modified in several places.

InputStream OutputStream IntroductionAn important set of interfaces (actually abstract classes) in IO flow operations is InputStream and OutputStream.InputStream字节输入流其最核心的一个方法是read()方法OutputStream字节输出流其最核心的一个方法是write()方法所有字节输入输都要实现read方法,所有字节输出流都要实现write()方法。字节流可以操作任意类型的文件(二进制或文本文件)Start by understanding several concepts:01机器码:只有机器才能识别0101串字节:拿英文来说明就是英文字符所对应的ASCII码(a==>97)字符:就是我们人类能识别的字符文字备注:每种语言有自己对应的字节码比如英文一个字符只占一个字节(ASCII编码),但是中文可能就会占两个字节(gbk/gb2312)或三个字节(utf-8)取决于使用何种编码格式。InputStream Abstra
