设计一个收银程序 checkCashRegister() ,其把购买价格(price)作为第一个参数 , 付款金额 (cash)作为第二个参数, 和收银机中零钱 (cid) 作为第三个参数. cid 是一个二维数组,存着当前可用的找零. 当收银机中的钱不够找零时返回字符串 "Insufficient Funds". 如果正好则返回字符串 "Closed". 否则, 返回应找回的零钱列表,且由大到小存在二维数组中. 当你遇到困难的时候,记得查看错误提示.阅读文档.搜索…

题目大意:有n张钞票,面值可能不同.你要买一件东西,可能需要找零钱.问最少付多少钱,并求出最少的钞票张数. 题目分析:定义状态dp(i,w)表示前i张钞票凑成w元需要的最少钞票张数.则状态转移方程为dp(i,w)=min(dp(i-1,w),dp(i-1,w-a(i))+1).其中a(i)为第i张钞票的面值. 代码如下: //# define AC # ifndef AC # include<iostream> # include<cstdio> # include<cstr…
