,6,4,2,4,3) to replace the (4,3) point with a color value of 2 o'clock, the arguments to the function and the local variables of the temp stack are pressed, and we simply use (4,3) to represent them. According to the function code, the point above the specified point (3,3) is searched first, because the (3,3) color value is 1, the (3,3) stack is pressed, and the point above is continued on the basis of the (3,3) specified point, at which point the color value is 0 non-conforming; the next specif

This article mainly introduces some of the functions of jquery discarded and its substitution function, we do in the development of the project must pay attention to, share to everyone reference. Earlier, the jQuery-1.7.2 version was used for better browser compatibility, but with the rapid development of major browsers and technologies, Even bootstrap new version is the need to introduce more than jQuery-1.9 version, representing the commonly used j

Drawing drawings in AutoCAD with similar shapes but with different sizes is a problem we often encounter, drawing in standard sizes, time-consuming and laborious. In fact, the purpose of some simple sketches is only to enable the processing workers to understand the size and shape of the parts, so in order to improve efficiency, we can use the "word substitution" method to modify the already drawn approximate graphics to quickly get the new sketch. A

Liskov substitution principle LSP is one of the basic principles of object-oriented design. As mentioned in the Rys replacement principle, subclass can certainly appear where any base class can appear. LSP is the cornerstone of inheritance reuse. Only when the primary class can replace the base class and the functions of the software unit are not affected can the base class be reused, the category class can also add new behaviors based on the base cla

This article to PHP beginners to talk about two examples of PHP character substitution function, one is str_ireplace () one is substr_replace () These two functions are more useful, there is a need for reference. String substitution techniques can be implemented using the following two common functions: the Str_ireplace () function and the Substr_replace () functionStr_ireplace () functionReplaces the strin

php function Preg_replace () Prototype: Mixed preg_replace (mixed $pattern, mixed $replacement, mixed $subject [, int $limit]) The PHP function Preg_replace () is more powerful than the C function. The first three parameters can be used arrays, the fourth parameter $limit can set the number of substitutions, the default is to replace all. Code 6.7 is an application instance of an array substitution. php function Preg_replace () code 6.7 array

Definition 1: if each object of type T1 is O1, there is an object O2 of type T2, so that all program P defined in T1 is replaced with O1 for all object O2, and the behavior of program p does not change, then type T2 is a subtype of type T1. definition 2: All references to base classes must be able to transparently use objects of their subclasses.problem Origin: There is a functional P1, which is done by Class A. Now need to extend the function P1, the function of the extension is P, where p is c
