Title: Counts the number of occurrences of a number in a sorted array.For example: Sort array {1,2,3,3,3,3,4,5} and number 3, because 3 appears 4 times, so output 4There is one of the simplest algorithms to traverse. But it's more efficient than it

During the development process. The handling of arrays and collections is the most worrying. Some operations are typically handled with a for or foreach. Here are some commonly used sets and arrays of operation functions.First, for example, 2 sets,

The VAR keyword is a new feature of c#3.0, called inferred type (in fact, the definition of a weakened type).VAR can replace any type, and the compiler will determine what type you want to use, like object, based on the context, but the efficiency

Operator overloadingThe so-called operator overloading is the ability to allow a user to write an expression using a user-defined type .For example , it is usually necessary to write code similar to the following , Add two numbers into the river ,
