JavaScript files needs to be introduced by some components, Yii will introduce this URL (once) instead of individual script files. Second, we need to use some tools to combine (and compress) JavaScript files into a separate file and save itjs/all.js. The same technique applies to CSS files. With the help of Google AJAX Libraries API, we can improve the page loading speed. For example, we can introducejquery.jsInstead of from our own server. To do this, we first configurescriptMapAs follows, $

version. The system creates a corresponding new class for each class that becomes a zombie. When a message is sent to a zombie object, the system can then know which class the object belongs to. If all the zombie objects are grouped into the _nszombie_ class, the original class name is lost. The work of creating a new class is done by the run-time function Objc_duplicateclass (), which copies a copy of the structure of the entire _nszombie_ class and gives it a new name.

Simplify the problem! If you do not consider the color, you can just look at four people and four A cards. Because all cards are of equal probability, you can consider other cards instead of.Assume that all a is the same:One person takes four A: Four (each person is a possibility) or C)Three persons in one person, and one other person: 3*4 = 12 (C (3100) * C (1300), indicating the order of existence, that is, and are two different types, or C () * ))One person and two others: 1 + 2 + 3 = 6 (C ()

Java record-52-Java Collection class setThe java. util package contains some of the most exciting enhancements added in java 2: class sets. In addition to the class set, java. util also contains various classes and interfaces that support a wide range of functions. Their applications include the generation of pseudo-random numbers, operations on dates and times, observation events, operations on the counterpoint set, and marking strings. Java. util ha

should be based on the specific needs of the test plan.When you write a hash method, you should use an algorithm that is fast and has a low probability of collision with the hash code.9, the class family mode can hide the implementation details behind a set of simple public interfaces.Class families are often used in system frameworks.Be careful when inheriting subclasses from the common abstract base class of a class family, if you have a development document, you should read it first.10, thro
