Preface
Keyword: digitalclock Date Format
The digitalclock of Android does not set the attribute or method of the output format, but it can be implemented through inheritance and rewriting. For details, see the code in the body.
Body
I. Requirements
Modify the time output format to show only hours and minutes.

By looking at the source code, you only need to modify the following two lines of code and copy them all:

calculated as 3M13=M1*M2*M3, the goal is to find the minimum number of multiplication operations for M13. m13=min{m1*m23+r1*r2*r4,m12*m3+r1*r3*r4}=min{1100,5250}=m12*m3+r1*r3*r4=1100similarly m24=m2*m3*m4=min{m2*m34+r2*r3*r,m23*m4+r2*r4*r5}=min{10500,3000}=3000;(3) The final result of calculating the number of multiply matrices is 4:M14=min (M13*M4+R1*R4*R5,M12*M34+R1*R3*R4,M1*M24+R1*R2*R5) ={3000+10000, 5

struct CATRANSFORM3D

CGFloat M11 (x scale), M12 (y Shear), M13 (), M14 ();
CGFloat M21 (x Shear), M22 (y scale), M23 (),
volumes of B and A to R respectively. The total shear volumes are the total shear volumes of R. Expressed:
R = g * m21 + B * m31 + A * M41;
G = r * m12 + B * M32 + A * M42;
B = r * M13 + G * M23 + A * m43;
A = r * m14 + G * M24 + B * m34;
3. Color rotation: The description of color rotation is complex, that is, in the image pixel, two of them are used to calculate the result around the other one according to a certain angle, is the color rotation. Ta

, the indirect nature of each access is more than one layer. In addition, this pointer should be used to calculate the memory size occupied by each object. Also, the pointer itself needs to be initialized (within the constructor of the handle class) to point to the dynamically allocated implementation object, it also bears the overhead caused by dynamic memory allocation (and subsequent memory release ).---- See clause 10.
For protocol classes, each function is a virtual function, and all calls
