Exercise: order line

Write a function function formatOrder(item, price, count) that returns an order line of the form "<count> x <item> = <total>", where the total is price * count. There is exactly one space between the parts, and x is the small Latin letter.

• formatOrder("tea", 50, 3) → "3 x tea = 150"
• formatOrder("green tea", 70, 1) → "1 x green tea = 70"
• formatOrder("cake", 120, 0) → "0 x cake = 0"

Constraints: item is a non-empty string of Latin or Russian letters and spaces, price and count are whole numbers from 0 to 1000; if price or count is 0, the total is 0.

Do not add extra imports unless the task says so explicitly.
