For example, Party A, Party B, and Party C each have a cost of 100 yuan. Based on the above-mentioned winning/losing relationship, let's play with it:
A lost 50 yuan to B and 50 yuan to CB lost 100 yuan to CC lost 100 yuan to
If you just play, it's easy to figure out who winsBut what would they do if they kept the winning or losing relationship and the winning money was invested in another round of gambling?
We can write a single machineProgramLook, for ease of computing,
;return ax * by - ay * bx;}bool inTri(int x, int y, int x1, int y1, int x2, int y2, int x3, int y3) {return abs(cross(x1, y1, x2, y2, x3, y3)) == abs(cross(x1, y1, x2, y2, x, y)) +abs(cross(x1, y1, x3, y3, x, y)) +abs(cross(x3, y3, x2, y2, x, y));}
The area is relatively intuitive:

The known nonlinear equations are as follows:3 * x1-cos (X2 * X3)-1/2 = 0
X1 ^ 2-81*(X2 + 0.1) ^ 2 + sin (X3) + 1.06 = 0
Exp (-X1 * x2) + 20 * X3 + (10 * pi-3)/3 = 0
The accuracy of the solution must reach 0.00001.

Mean value algorithm of MA, EMA, SMA, DMA, TMA, WMA6MA, EMA, SMA, DMA, TMA, WMA6 average algorithms are often used in various indicator formulas, but most beginners may not understand their specific differences, organized as follows.MA (x,n) simple arithmetic averageThe N-day moving average of x, not the weight, the average calculation. The algorithm is:(X1+X2+X3+.....+XN)/nFor example, MA (c,20) represents the average closing price of 20th. C means c

The main operations include: = (Assignment), +=,-=,*=,/=,%=.
Assignment = operation is very simple, the basic is to two types of variables, one of the values assigned to the other.

Title DescriptionSeveral days ago, a beast caught a beautiful princess and the princess were put in prison. To rescue the princess, a prince who wanted to marry the princess set out immediately. Yet, the beast set a maze. Only if the Prince find out the maze ' s exit can he save the princess.Now, here c
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;
The specific impl

X is an object, subset is a logical expression that retains elements or rows, and Na is substituted for missing values.
Select is the selected range and should be less than X.>x
