On an electronic exchange, investors issue buy and sell orders for certain stocks, indicating the greatest purchase price or the lowest sale price they are ready to pay as well as the number of shares they desire to trade at that price. Create a programme that utilises priority queues to connect buyers and sellers, then simulate and test it. Continually execute transactions anytime a new order can be matched with an existing order or orders by maintaining two priority queues, one for buyers and one for sellers.
