E-Mart Product Ranking

While the database is being transferred, an unknowing customer logs onto the website and browses some of E-Mart's items. Given a server log in chronological order, determine which items were shown to the customer.
E-Mart has an unusual way of displaying items:
If a customer views the first item, they will be shown the cheapest item in the database;
If a customer is currently viewing the kth cheapest item, viewing the next item will display the (k+1)th cheapest item;
If multiple items have the same price, they are ordered alphabetically ascending;

Solve the problem:
def getItems(entries): """ :type entries: List[str] :rtype: List[str] """
