问题描述： 假设一个商店，它有一个货架和一个仓库，当货架上的商品数量少于一定的数目时，从仓库运一定数量的商品摆到货架上，当仓库里的商品的数量少于一定的数目时，购买商品把仓库填满，商品的出售要按照商品的生产日期来，快要过期的商品要先出售。 解决问题的方法： 用了两个栈和 一个队列，把队列当作仓库，用一个栈作为货架，把另一个栈当作临时的存储箱。当要往货架上添商品时，先把作为货架的栈中的元素全都压到作为存储箱的栈中，再把仓库中的元素压到存储箱中，然后再把存储箱中的所有元素都压到货架上，这样，就能保证快要过期的商品先被出售。-Problem description : Suppose a shop, which has a shelf and a warehouse, when the merchandise on the shelves less than a certain quantity of the number, a certain number from the warehouses of goods on the shelves, when the warehouse volume of goods is less than certain number, purchase goods warehouse filled, the goods according to the sale of commodity production to date, is about to expire first sale of goods.
