题目链接:cid=80117#problem/E">click here~~ [题目大意] 农夫JF在n天中每天的花费,要求把这n天分作m组.每组的天数必定是连续的.要求分得各组的花费之和应该尽可能地小,最后输出各组花费之和中的最大值 [解题思路]: 经典的最小化最大值问题,要求连续的m个子序列,子序列的和最大值的最小,枚举满足条件的m的最小值即为答案.因此二分查找. 1.能否把序列划分为每一个序列之和不大于mid的m个子序列, 2.通过用当前的mid值能把天数分成几组, 3.比較mid和…

题目:http://poj.org/problem?id=3273 思路:通过定义一个函数bool can(int mid):=划分后最大段和小于等于mid(即划分后所有段和都小于等于mid) 这样我们转化为求 满足该函数的 最小mid.即最小化最大值,可以通过二分搜索来做,要注意二分的边界.WR了好几次. 代码: #include<iostream> #include<string> #include<cstdlib> #include<cstdio> u…
