There are different qualities of wine in the shop, and all of which has a rating describing the qualities. All the ratings are larger than 0 and smaller than 1,000,000. Everyday nearly Q people will go to his shop and buy a bottle of wine because of his kindness. Once a customer want an X qualified rating but there are no such one, Sempr will sell him a better one with the smallest rating. But the boss of the shop is Snowwolf, you know, so if no wine has no more than Y qualified ratings better than the customer's request, Sempr will say sorry to them. Every morning, Xiangsanzi will send N bottles of different or same qualified wine.
