Extracted text: Create a sequence diagram showing the interactions of objects in a group diary system, when a group of people are arranging a meeting. Assume there are 3 participants in the meeting, one of whom is the meeting organizer. The organizer suggests a 'window' in which the meeting should take place and the participants involved. The group diary communicates with the diaries of the participants in turn, modifying the window accordingly as there availability is known. So, if the organizer suggests a window of 18th-19th June, the group diary consults the organizer's diary (D1) and finds availability on these days. D2 is then contacted with that availability, not the original window. If there are no mutually available dates in the window, the system reports this to the organizer. Otherwise, a date is selected, entered in all diaries and confirmed to the organizer. 1) Create Sequence Diagram using UML Notations
