Analysis:This is called the Maze Search to find the shortest problem, and the output to include the path, is a typical search question it. The problem I used is BFS search, the first need to establish a structure to store the coordinates to each location and the total time spent, using BFS of course to use the priority queue, in this queue, spend less time on the team head, also need to build a structure to store the shortest route. , and then output the path in turn when the shortest path is f

12.1 css3 provides deformation support CSS 3 supports common geometric transformations for HTML components, including rotation, scaling, skew, and displacement. 4. You can also use the transformation matrix for deformation. Css3 provides the following two attribute values for deformation support. Transform: This attribute is used to set deformation. This attribute supports one or more deformation functions. Css3 provides the following deformation functions. Translate (TX [, Ty]): This function s

are like △x and △y. x’ = x+Δxy’ = y+Δy Transform: translate (tx, ty); In CSS 3 is equivalent to transform: matrix (, tx, ty). Note that no unit is required when matrix is used, the default is px, while the translate requires units, which can be px, em, and so on.Zoom and stretch original size up to 1.5 times in length and width If the matrix (Sx, Sy,) parameter is provided, that is, a or d is not equal to 1, for example, a =

translation, into a x+tx,y+ty point. Very simple. If mathematically speaking, TX and Ty are like Δx and Δy. X ' = X+δxY ' = Y+δy Transform:translate (TX, Ty) in CSS 3 is equivalent to Transform:matrix (1,0,0,1,tx,ty); Note that when using the matrix, you do not need units, the default is PX, and translate need units, It can be a unit such as PX and EM.Scaling and stretching the original size 1.5 times times longer and widerIf the parameter matrix (

setRotate (float degrees)public void setRotate (float degrees, float px, float py) The degrees parameter specifies the rotation angle. If it is greater than zero, it is clockwise. If it is less than zero, it is counterclockwise. The px parameter and py parameter are used to specify the center of rotation. The default value is (0, 0), that is, the upper left corner.Scaling operation There are 6 methods related to the scaling operation in Matrix, public boolean postScale (float

"vertically" into multiple base tables. For example: The student relationship student (sno,sname,ssex,sage,sdept), is divided into SX (sno,sname,sage) and Sy (sno,ssex,sdept) two relationships. The original table student is the result of the natural connection of the SX table and the SY table. If you create a view student:CREATE VIEW Student (sno,sname,ssex,sage,sdept) as SELECT

enable users to view the same data in multiple anglesThe view mechanism enables different users to view the same data in different ways, and this flexibility is necessary when many different kinds of users share the same database.3. Views provide a degree of logical independence for refactoring databasesThe physical independence of data means that the user's application is not dependent on the physical structure of the database. The logical independence of data is that when a database is re-con

Supports a wide range of QOS, ACL, and hardware-based access control lists.2) L2 aggregation switch:The design principles of L2 switches aim to improve the manageability, reliability, and scalability of the network, and configure the fully Gigabit ports of the network management layer switch GSM712.

BGP experiment, you can even use this configuration to establish full-network connectivity, and then create a tunnel port to implement the experiment topology. During remote configuration, you can save multiple configuration files and switch between them. The configuration file named router-confg can be used as a final backup-if you accidentally delete the configuration, there will still be an available configuration after the system restarts.Conclusion: The initial enchanting phenomenon is cau

port is in the err-disable State because it detects a loop on port 20th.
