Question: (such as question)
Input and Output: (such as the question)
Solution:
1. Because each button is pressed twice, the effect is the same. Therefore, each button is in the status of 2 ^ 4 = 16.
2. Because the electric lamp system has a personality and every six cycles, the status of the first six lights corresponding to the 16 states of the four buttons is enumerated. Then the analysis finds the rule:
-1 and 2 are equivalent to 3;

Vectors are the standard tool for 2D and 3D Mathematical research, and in 3D games vectors are the basis. Therefore, it is very important to master some basic concepts and properties of vectors and common operation methods. In this blog, horse and everyone to review and learn about the Unity3d in the common 3D mathematics knowledge.I. Vector concepts and basic definitions 1, mathematical definitions of vectors

vector Container
Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to the vector as a container because it can contain other objects. All objects in a container must be of the same type.
Before using vectors, you must include the
