small problem of the combination of solutions, you can get the answer to the original question. Small problems are usually similar to the original problem and can be solved recursively using the divide-and-conquer strategy.

The basic idea of divide-and-conquer algorithm is to decompose a problem of size n into a small sub-problem of K, which is independent and the same nature as the original problem. The solution of the problem can be obtained by finding out the solution of the sub-problems.When we solve some problems, because these problems to deal with a considerable amount of data, or the process is quite complex, so that the direct solution in time is quite long, or simply can not be directly obtained. For this

the parent class, and at the end of the subclass destructor implementation, the destructor of the parent class is automatically called. The destructor of the parent class is called even if the subclass does not provide its own destructor.Because the instance is freed until the destructor of the instance is called, the destructor can access all the properties of the instance and can modify its behavior based on those properties (such as finding a file that needs to be closed).destructor Practice

automatically called one step before the instance is released. You cannot actively call your own destructor. The subclass inherits the destructor of the parent class. At the end of the implementation of the subclass destructor, The destructor of the parent class is automatically called. Even if the subclass does not provide its own destructor, The destructor of the parent class is always called. Because the instance is released only when the destructor of the instance is called, The Destructor

before the instance release occurs. You are not allowed to invoke your own destructor actively. Subclasses inherit the destructor of the parent class, and at the end of the subclass destructor implementation, the parent class's destructor is automatically called.　　Destructors for a parent class are always called, even if the subclass does not provide its own destructor.　　Because the instance is not freed until the instance's destructor is called, the destructor can access the properties of all
