OJ Problem 3453 c# simple class inheritance

Title description

Writing code implementation: Three classes Bird, Mapie, and Eagle are defined. Among them, Bird is an abstract class, which defines an abstract method Eat(). The Mapie class and Eagle class are derived classes of Bird. The Eat() method is overridden in the Mapie class, and an Eat(int time) method is overloaded. The Eat() method is also rewritten in the Eagle class.
