The test instructions of this problem is to give some rectangles, asking the area of these rectangles to be covered, that is, the rectangles may intersect.
Because of the small amount of data, the problem can be divided by the method of sorting the input coordinates.
As the following code
/* id:sdj22251 prog:subset lang:c++ * * #include
There is also a rectangular cut, the principle is to split the intersecting rectangle into a few small rectangles, and then the last of all the rectangles wil
increase or decrease the number of books you have bought.
The parameters to be processed are the number of purchased volumes, so recursion must be related to these five parameters. You can sort the parameters in ascending order. The number of parameters not 0 is discussed to find all possible discount types. Then, the minimum price is obtained from the current discount type.
State transition equation:
(X1, x2, X3, X4, X5) indicates the number of purc
Reliability Analysis
Sfta (Software Fault Tree Analysis) software fault tree analysis.
Software Fault Tree Analysis (sfta) is a top-down software reliability analysis method ), in particular, the incidents that have a significant impact on the safety and reliability of personnel and equipment begin to trace down the causes of the incidents until the basic incidents (bottom incidents ), to determine the possible combination modes and/or probability of occurrence of software faults.

By observation, the 360 installation of animation is a few rounds of continuous amplification process. That is, the concentric circle radius of different amplification.
I use five circles to make a similar effect, in order to differentiate effects, I set five circles to use different brushes.
The following are the specific code:
This five radius is a global variable.int x1 = 200;int x2 = 100;int x3 = 50;int x4 = 150;int x5 = 250;
