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> #…

题目链接:http://poj.org/problem?id=2586 题目大意:(真难读懂啊)给你两个数,s,d,意思是MS公司每个月可能赚钱,也可能赔钱,如果赚钱的话,就是赚s元,如果赔钱的话,就是陪d元.现在告诉你只要是连续的5个月,就亏钱(亏多少不知道),问你MS公司全年能够赚多少钱,如果赚不了钱的话,就输出“Deficit” 贪心:我们说,输出的最终结果是f(x,y)=x*s-y*d,也就是说现在要求得x,y使得f(x,y)具有最大值. 当s,d,x+y给定时,x越大,则赚的钱越多.…
