Enum (enum) Enumerations are a collection of named Integer constants, which are common in everyday life.For example, the sunday,monday,tuesday,wednesday,thursday,friday,saturday of the week is an enumeration.The descriptions of enumerations are similar to structs and unions in the form of:Enum Enumeration Name {identifier [= integer constant],identifier [= integer constant],...identifier [= integer constant],Enumerate variables;If the enumeration is not initialized, that is, when the "= Integer

The differential constraint system is only one application of the shortest path algorithm, there is no new algorithm, but the determination of the specific problem of the method of building the map The problem solved by the differential constraint system is the solution of the inequality group: x1-x2 x1-x5 x2-x5 x3-x1 x4-x1 x4-x3 x5-x3 x5-x4 This is an inequali

As shown in the left figure, the amplitude of x0 is not affected by the amplitude of x0, at the same time, it is affected by four points (x1, x2, X3, X4) from the front, back, left, and right around it (to simplify it, we ignore all other points, the influence of these four points on A0 can be said to be equal opp

This article is purely original. content source: Peking University's video teaching .. It is really not easy to understand the proof of this theorem. After understanding this theorem, I personally think that the Euler function is really not difficult... Theorem: If m and n are twoMutual QualityThe integers x and y simplify the remainder system by Modulo M and N respectively, then n * x + M * y simplifies the remainder system by M * n. Alternative Syntax: x = {x1, x2, X3,

The basic content of the unique decomposition theory: Any positive integer greater than 1 can represent the product of several prime numbers, and the representation method is unique. In other words, a number can be uniquely divided into the product of a prime factor. Therefore, this theorem is also called the unique decomposition theorem. Example: 50 = (2 ^ 1) * (5 ^ 2) The general idea of the question is to create a prime number table. E = {, 0, 0 ......} The following are two questions. Let's

Let's take 1 + x2 as an example. As we have already said before, X indicates the weight, and X indicates the weight. Here is a weight with a mass of 2.1What does it mean? 1 indicates that
