题目链接: https://vjudge.net/problem/POJ-2586 题目大意: MS公司(我猜是微软)遇到了千年虫的问题,导致数据大量数据丢失.比如财务报表.现在知道这个奇特的公司每个月不是盈利就是亏损(废话),而且无论是盈利和亏损都有一个定值(亏少了它还不干).经过ACM组织的分析,在一年中任意连续的5个月,它都是亏损的,但是全年就不一定亏损了.现在给你盈利和亏损的定值s和d,请求出它一年能得到的最大利润!如果亏了,就输出Deficit! 思路: 一开始暴力一发,枚举12个月的…

题目链接. 题目大意: 题目相当晦涩难懂啊. 一年的12个月,每5个月统计一次,如从1~5,2~6,3~7,...,8~12共统计了8次,已知每次都deficit,问这一年有没有盈利的可能. 一个月surplus只能是s,deficit只能是d,不能是其它的值. 分析: 用贪心,先计算1~5,让每个月都盈利,然后从第5个月向前deficit,直到1~5的和为deficit.继续2~6,3~7....,8~12. 最后统计全年是否盈利. AC代码如下: #include <iostream> #…

链接:http://poj.org/problem?id=2586 题意:大意是一个公司在12个月中,或固定盈余s,或固定亏损d.但记不得哪些月盈余,哪些月亏损,只能记得连续5个月的代数和总是亏损(和<0算亏损),问全年是否可能盈利?若可能,输出可能最大盈利金额,否则输出“Deficit". 题解:看了网上的题解,基本上都说是贪心,但我不知道怎样贪心,只不过按自己的想法去做(做的时候不够细心,忽略了细枝末节).由于连续5个月必须亏损,所以就但看5个月内,亏损最少的情况,是1*d与4*s,是…
