problem DescriptionCDFPYSW loves playing a card game called "Hearthstone". Now he had N cards, he wants to split these cards into 4 piles.Let's assume the number of cards in each pile is A1, A2, A3, A4. It must be satisfied that:a1 * K1 = a2 + a3 + a4 A2 * k2 = a1 + A3 + a4 a3 * K3 = A1 + a2 + A4 A1, a2, A3, A4 Must be positive Because cdfpysw are clever, there must be a-to split there card. Can you tell CDFPYSW?InputThe first line was an integer T,

of your turn, you draw a-card from the top of the the card deck. You can use any of the cards in your hands until to run out of it. Your task is to calculate the probability so you can win in this turn, i.e., can deal at least P damage to Your enemy.Inputthe first line is the number of test cases T (tThen come three positive integers P (pOutputfor each test case, output the probability as a reduced fraction (i.e., the greatest common divisor of the numerator and denominator is 1). If the answer

Recently learned some about three-dimensional space rotation related knowledge, to comb the memo.The rotation of the three-dimensional space (3D Rotation) is a very magical thing: if a rigid body in three-dimensional space for any rotation, as long as the center of rotation

As shown in the following illustration, you can choose this option when dealing with the default rotation direction of the screen, which is 4 directions up or down.
The planning requirement is that the game uses a horizontal screen, but requires support in two directions to automatically rotate, as shown in the following figure, my settings are like this.
Default orientation* Auto Roation indicates that the game supports automatic

1. The object's specific rotation around which axis, corresponding setting value;Transform.Rotate (new Vector3 (1,0,0)); //rotation around x-axis//By default, the object rotates around the XYZ axis of world coordinates, that is, the object rotates around the y-axis of the world center 0,0,0. The statement is equivalent to transform. Rotate (new Vector3 (1,0,0), space.world); If you need to rotate, change th

2D impeller rotation and 2d impeller rotation based on HT for Web vector
Previously, some static elements were used in topology applications. Today, we will design a moving element, impeller rotation, on the topology.
Let's first look at what the impeller model looks like.
From the model perspective, this impeller model has three blades, each of which is irregu

When it comes to the rotation of objects, it may be reminiscent of the concept of object angles. The rotation implementation of the object is actually a position transformation using the angle change of the object, in the "Silverlight Blend Animation Design Series II: Rotation animation (RotateTransform)" In the article on the object of the different angle trans

Rotation formula of a plane point and a plane rotation formula
Definition: the rotation of a point O above a plane is to make any pair of corresponding points P and P on the plane equal to the line segments connected to a fixed point O, that is, | OP | = | OP '|, And the directed angle
Take the Cartesian coordinate system for the transformation formulaOrigin O

Point rotation transformations in the same coordinate system (1) and point transformations in different coordinate systems (2) have plagued me, they are two different concepts, but the form is very similar to the two-dimensional space as an example to do the next deduction, deepen understanding.The point rotation transformation under the same coordinate system is better understood and is a rotational transf

The rotation of the three-dimensional space can be represented by Euler's angle, rotation vector, rotation matrix, and four-dollar number.The first is the Euler angle notation, which we can use to rotate around an axis.A rotational vector is a rotating axis and a rotational angle to represent rotation.The rotation matr
