Не проходит 5 тест:
Failed case #5/5: Wrong answer
Дополните класс Person из задачи «Имена и фамилии — 2» конструктором, позволяющим задать имя и фамилию человека при рождении, а также сам год рождения. Класс не должен иметь конструктора по умолчанию.
При получении на вход года, который меньше года рождения:
методы GetFullName и GetFullNameWithHistory должны отдавать "No person";
методы ChangeFirstName и ChangeLastName должны игнорировать запрос.
Кроме того, необходимо объявить константными все методы, которые по сути ими являются.
