The department responsible for reporting the iron box cleans up the iron box every 5 years, pours the ashes in the box into a large pit and buries them together with the iron box. Smoke floated and they left the place where they used to live quietly.

The headquarters location has not yet been determined and filed. It is difficult for the branch location to have a clear understanding of the whole picture of the case and make a decision to file the case.

The above design, as commented above, when executing the Resize method of SmartTest, if a rectangular object is passed in, when the height is greater than the width, the width will be automatically increased until it exceeds the height. However, if a square object is passed in, it will fall into a dead loop. The fundamental reason at this time is that rectangles cannot be the parent class of squares. Since there is a problem, they can be reconstructed so that both of them inherit from quadrilateral classes. The refactoring code looks like this:
