arithmetic basic theorem : any one natural number greater than 1 N, if n is not prime , then n can be uniquely decomposed into the product of finite prime numbersN = p1^a1 * P2^A2 * p3^a3 * ... * pn^an(Wherein P1, p2 、... pn is n factor, A1, A2 、... 、 an exponent of the factor respectively)Such decomposition is called the standard decomposition of NApplication:(1) A positive integer greater than 1 N, if its

= 79, then P may be P = 5 × 79 = 395, mr P can easily obtain X and Y. Therefore, if S is 84, Mr. s cannot be sure that Mr. P does not know X and Y, so S Is the number of sums that cannot be expressed as two prime numbers. (A) You can reduce the value range of S. 3. If there is only one prime number in X or Y and the number is greater than 50, then Mr. P can still solve X and Y only when he knows p. Let p be decomposed into the product of the following prime numbers: P = p0p1p2... in

dots (red pairs of parallel lines) that are crossed by parallel lines in the diagram. The diameter is highlighted in light blue.Clearly, it is not possible to determine the point pair of a convex polygon p diameter inside the polygon p. So the search should be done on the border. In fact, because the diameter is determined by the farthest distance of the polygon's parallel tangent, we only need to query the heel point. Shamos (1978) provides an O (n) time complexity algorithm for calculating n-

markup language. to support multimedia data types, the MIME data type information appended to the document is used in the HTTP protocol to identify the data type.Mime is an extension of multi-object Internet mail. It is designed to attach multimedia data to an email so that the mail client program can process it based on its type. However, when it is supported by the HTTP protocol, its meaning becomes more significant. It makes HTTP transmitted not only plain text, but also rich and colorful.Ea

Class A This sectionCodeThere are two wonders: 1. The destructor of A is protected, and there is no error prompt during compilation. 2. A's destructor are not virtual, But B's destructor is called at last. Shared_ptr is really eye-catching. Let's go to boost to find out what's going on. Start with the Statement of shared_ptr: Template Note that there are two variables, PX and Pn, to see how they are declared: T

Show a reference to a pointer and pointer using pointers to modify the pointer passed to the method to better use it. (The pointer to the pointer is not a two-dimensional array.)Why you need to use themWhen we pass a pointer as a parameter to a method, we are actually passing a copy of the pointer to the method, or it can be said that the passing pointer is the value of the pointer passing.If we have a problem modifying pointers inside a method, making changes in the method is just a copy of the
