STORE ACCOUNTING

We are writing a program module for an online shop that processes purchases.
The program receives the sold items as an array of objects; each object
contains the name of the item, its price and its category (see below).

1. Print the names and the number (the count) of all sold homeware accessories.
2. Print the total revenue (the sum of the prices of all sold items).
3. Print the average price of the items. Make sure that the price is rounded to 2 decimal points.
4. Print the name of the most expensive product.
