and is not consistent with the basic paradigm of the OOP - joining data and methods for handling them in a class. The static member allows class data that are not specific
Suppose you have two arrays of ints that are both of length n. Write a recursive C++ function that will return true if the arrays are the same (i.e., they contain identical values in the identical ord What is the difference between for-each loop and for loops ...
Most people forget that there are already static interfaces in the sense that a constructor function/class has two interfaces already, the constructor interface and the instance interface. interface MyFoo { method(): void; } interface MyFooConstructor { new (): MyFoo; prototype: MyFoo; staticMe...

Then, they introduced a new kind of stateless method bound to the class without access to the static instance and call it @staticmethod. In this case, python static is quite different from static in C++ / Java / C#. It's more like an unbound function using the class name as a...
