Write a class Example() such that it has a method that gives the difference between the size of strings when the '-' (subtraction) symbol is used between the two objects of the class. Additionally, implement a method that returns True if object 1 is greater than object 2 and False otherwise when the (>) (greater than) symbol is used. For example: obj1 = Example('this is a string') obj2 = Example('this is another one') print(obj1 > obj2) False print(obj1-obj2) 3
