题意: 有\(10\)种面值为\(1, 5, 10, 20, 50, 100, 200, 500, 1000, 2000\)的纸币,现在你要选最多的数量凑成\(p\)块钱. 分析: 同样分析问题的反面:设总金额为\(sum\),我们来求凑成\(sum-p\)所需要的最少的张数.那么剩下的就是凑成\(p\)的最多的张数. 如果没有\(50\)和\(500\)的面值的话,那么后一种面值都是前一种面值的倍数,显然贪心是可以的. 贪心的理由就是完全可以用大面值替换掉对应数量的小面值的钱,这样总钱数不变但…
题目链接 题意 : 给出一些固定面值的硬币的数量.再给你一个总金额.问你最多能用多少硬币来刚好凑够这个金额.硬币数量和总金额都很大   分析 : 长春赛区的金牌题目 一开始认为除了做类似背包DP那样子的DP外.别无他法 时空限制下是不可能DP的 众所周知背包DP问题贪心是错的 遂认定不是贪心方向 看到题解.真香~ 这种凑硬币问题.如果满足一个条件.那么贪心是正确的 当然和这道题目不一样.可贪心的是要求用最少的硬币凑出总金额 需要满足的条件是.可选择的硬币面额满足大面额是小面额的倍数 如果不满足上…

java学习脚印:深入java绘图机制 写在前面 封装性越好的类在使用时,只要清楚接口即可,而不应该让程序员了解其内部结构; 对于平常的绘图来讲,java绘图机制无需了解太多,但是朦胧容易产生错误,绘图操作包括了整个GUI的显示问题,遂花了一些时间来学习.整理下,本文主要基于[1][2]以及众多资料整理以及自我理解和实践加工而成(如有错误,请纠正我).这里所讲的很多技术可能已经过时了,你可以略过这些部分,但是像下面关键概念以及绘图指导意见部分还是应该掌握. 1.javaGUI的背景 java G…
