/* Write a recursive function to write a cryptographic polynomial, and the function should match the following function prototype: int Hermite (int n, int x) The Eris polynomial is defined as: n = 2 o'clock, H (n (x)) = 2*x* (H (n-1) (x))-(n-1)

1. Because C # can only inherit a class, to achieve the inheritance of different classes of attributes, you must use the interface (interface), the interface inside the method is public, but no concrete implementation;2. When an interface is

2.2Loop unrolling Looping expansionThe previous enum section describes the combination with the template, which throws a magical effect on the compiler recursion. The template itself can achieve recursive results without the need for enum mates.Test

Insert sort and merge sort are the first two methods of sorting in the introduction of algorithms.The idea of inserting a sort is that for an already sequenced array, a new element is now inserted and kept in order. So how to insert it, starting

1. Structural bodyFor the C + + language, there is little difference between structs and classes. The functionality that the class can implement, most of which can also be used with structs.In C #, however, we think of structs as a substitute for a

What we're going to do today is use C # to develop a desktop application that can log into the office and take personal informationThere are mainly httpclinet and regular expressions.Directis the interface of the program, enter the correct account
