Best Seller

You run a store and want to know where you make the most money and which items sell the most. You have a list of your items, how many times each has sold and how much profit you make each sale. Each item name is a single word. The total profit on an item is the number of sales times the profit of the item. Write a program that will take in this data and produce a sorted list using the following rules:

Sorting Rules:

• Sort items in descending order by total profit
• For items that have the same total profit, sort in descending order by number of sales
• For items that have the same total profit and number of sales, sort in ascending order by name

There will be an unknown number of inputs that consist of the triple itemName numberOfSales profitEachSale, with each triple on its own line, and each value on a line is separated by a single space. The itemName is a single word and the format for each input line will be:

itemName numberOfSales profitEachSale

Display the sorted list, with each item on its own line. The format for displaying the item will be:

$totalProfit – itemName/numberOfSales

There is a single space before and after the dash, and the profit value must have exactly two decimal places.
