degrees around the coordinate origin. The value is positive clockwise.Parameters: Degrees is the rotation angle, px and py are the coordinates of the specified rotation center (px, py)
Example:
Rect rect = new Rect(50,0,150,50); canvas.translate(200, 200); for(int i = 0; i
Running Effect:
Code Analysis:
Here, we first call translate (200,200) to move the coordinate origin of the canvas to (200,200) and then draw the canvas.The drawn results can be completely displayed o

I am a rubber and plastic product manufacturer. In February, the organization leader asked me to develop a production process data checklist to check the accuracy of the process data. The basic principles of the report are as follows:Subsequent processes: number of genuine products today + number of decommissioned products in subsequent processes today = number of genuine products in this process today + number of items retained in this process today-number of items retained in this process yest
Button
Software:Flash MX 2004
Effect:We want to do a flexible button, the mouse moved to the button, it will be flexible, the mouse moved away, the opposite.

principle:First, we need to set the maximum value of the mouse on the MC, setting the initial value. The elastic setting of resistance, the speed of elasticity. Set the initial value of the effect, and then calculate the size of the loop is to make the button elastic rathe
) indicates the depth from the starting node to N nodes in the state space, and H (n) indicates the straight line distance from the position of the map where n nodes are located to the target position. Ah! One is the state space and the other is the actual map. Do not make a mistake. In detail, there is an object A. The coordinates on the map are (XA, ya), and the coordinates of the target B to which a wants to reach are (XB, Yb ). When you start searching, set a Start Node 1 to generate eight c

In this example, g (n) indicates the depth from the starting node to N nodes in the state space, and H (n) indicates the straight line distance from the position of the map where n nodes are located to the target position.

order, and the matrix should be arranged in the order of x y z, then multiply by Z x Y). Assume that the Z angle is rotated by the Z axis, the X angle is rotated by the X axis, and the Y angle is rotated by the Y axis, then the matrix formula is (in which CZ represents cos (z) SZ represents sin (z )):
CZ * Cy + SX * Sy * SZ * CX-sy * CZ + SZ * SX * Cy ------------ right ---> X

to be divided into two teams to carry out tug-of-war competition, require the difference between the two teams not more than 1, and the weight and as close as possible.Idea: first by weight from small to large, and then the first half of a team, the latter half of Team B, calculate the difference in weight as the current minimum value. Generate two random number x, Y, as the number of players in the exchange, that is, the team a X players to Team B, the team Y Team B to the team A, check the ex

In fact, at the beginning, we wanted to use dir as a parameter and search based on the map condition, but it was processed with while in recursion. It was hard to process the backtracking of map from 0 to 1.
The code that hurts is tangled ..
Code:# Include # Include # Define min (A, B) A> B? B:
# Define Max 1E + 6

This was not the case at the beginning, and the running result was correct, but the memory was too large. Baidu used other people's methods. In fact, they only stored the values below, so I opened an dis [] [] [] array on the basis of the original one. To be honest, this is the first time I used a 3D array, I just stored the following and submitted the AC! Heheh ·······
I used to find a KFC and use BFS once, so the memory is too large. It seems that the storage can reduce a lot of operations and
