A stock order is an order to buy or sell a given quantity of stocks of a specified company. Person willing to buy or sell a stock will submit an order to a stock exchange where it is executed against the opposite side order of the same company i.e., buy order is executed against a sell order and vice-versa. The criteria for execution of stock orders is - they should belong to the same company, they are opposite sides ( Buy vs Sell), and an stock order is executed against the first available stock order. The left-over quantity, after execution, is called remaining quantity. For example, if a buy order of quantity 10 is executed against a sell order of quantity 4, the remaining quantity of buy and sell orders are 6 and 0, respectively. The status of an order is OPEN if the remaining quantity is greater than zero, otherwise it is CLOSED (i.e. remaining quantity = 0). Your task is to implement stock order execution system which takes stock orders as input from a CSV file, processes them and prints, as output, the status, remaining quantity of all the executed orders.
