My Calendar II. Implement a MyCalendarTwo class to store your events. A new event can be added if adding the event will not cause atriplebooking. Your class will have one method, book (int start, int end). Formally, this represents a booking on the half open interval [start, end), the range of real numbers x such that start <= x < end.
