If everyone quotes the average price of the first period in the first round, it will lead to the skyrocketing price of this period. Generally, the first quotation is generally very low, and the second quotation and the third quotation are gradually increased, so that the price will not skyrocket.

Auction time

According to the date stipulated in the tender announcement, the tender process is very simple. The bidding process lasts for six hours, starting from 9: 00 am, and the average price of bidders at that time is broadcast at 1 1 and 13 am respectively. At the end of the bidding on 15: 00 in the afternoon, each bidder will have a chance to make a bid and a second chance to revise the price, so that the bidder can make a deal at a reasonable price. Determine the final transaction according to the principle of price priority and time priority.
