There are multiple VM types, each with an initial stock count. A sequence of customers rent one VM at a time.

Each customer always rents from the VM type with the highest remaining stock. The revenue from a rental equals the sum of the current highest stock and the current lowest non-zero stock across all VM types. After the rental, the chosen VM type loses one unit of stock.

Return the total revenue after serving customerRequests customers.
