题目:POJ3273.洛谷P2884. 题目大意:有n个数,要分成m份,每份的和要尽可能小,求这个情况下和最大的一份的和. 解题思路:二分答案,对每个答案进行贪心判断,如果最后得出份数>m,则说明答案在[mid+1,r]内,反之在[l,mid]内.我的二分上界是所有数的总和,所以时间复杂度$O(n\log (\sum_{i=1}^{n}a[i]))$. 结果我贪心没考虑全,爆了一发O(≧口≦)O C++ Code: #include<cstdio> using namespace std…

POJ 3273 Monthly Expense 此题与POJ3258有点类似,一开始把判断条件写错了,wa了两次,二分查找可以有以下两种: ){ mid=(lb+ub)/; if(C(mid)<=m) ub=mid; ; //此时下限过小 } out(ub);//out(lb) 我一开始是写的下面这种,下面这种要单独判断lb和ub的值,因为用下面这种判断lb,ub都可能成立 ){ mid=(lb+ub)/; if(C(mid)<=m) ub=mid; else lb=mid; } if(C(…
