Scenario We've showed you recently how to extend Stack possibilities by dening a new class {i.e., a subclass] which retains all inherited trails and adds some new ones. Your task is to extend the Stack class behavior in such a way so that the class is able to count all the elements that are pushed and popped [we assume that counting pops is enough]. Use the Stack class we've provided in the editor. FollowI the hints: - introduce a property designed to count pop operations and name it in a way which guarantees hiding it; . initialize it to zero in side the constru ctor: - provide a method which returns the value curreny assigned to the countertname it get_c'.ounter E} ]. Complete the code in the editor. Run it to check whether your code outputs _'l.{l.
