A high level description of an auction application is provided below. Read the description and answer the question that follows. Feel free to use your imagination to fill in specific details in case they are not provided or if you aren't familiar with the auction domain.
An auction application involves buyers, sellers, and other users. Buyers and sellers must have accounts in order to place bids, purchase items, create a new auction, or ship items. Other users may use the auction application to search for items or browse through categories.
An auction must be created for an item to be sold in a certain category. According to Wikipedia, an English auction "is the type of auction commonly used by the English auction houses like Sotheby's, Christie's, and Phillips. Participants bid openly against one another, with each bid being higher than the previous bid. The auction ends when no participant is willing to bid further (and the auction time is over), or when a pre-determined buy-out price is reached, at which point the highest bidder pays the price. The seller may set a reserve price and if the auction fails to have a bid equal to or higher than the reserve, the item remains unsold."
Question: Draw an activity diagram showing a typical workflow for a buyer and seller in the same diagram. Use separate swimlanes for the buyer and seller.
