Since new is inconvenient, I would like to minimize the use of new, in the implementation of the linked list class, encountered in the case of new, try to use the new method.If you do not use new, pointers need to point to the object, when

Model definition: The strategy model defines the algorithm family, which is separately encapsulated to allow them to replace each other, and this mode allows the algorithm to be changed independently of the client using the algorithm.For example,
