题意: 将\(n\)个数分成\(m\)段相邻区间,每段区间的长度为\(\left \lfloor \frac{n}{m} \right \rfloor\),从每段区间选一个最大值,要让所有的最大值之和大于\(k\).求最小的\(m\). 分析: 预处理RMQ,维护区间最大值. 然后二分\(m\),将每段区间最大值加起来判断即可. #include <cstdio> #include <cstring> #include <algorithm> using namespa…

Problem Description YaoYao has a company and he wants to employ m people recently. Since his company is so famous, there are n people coming for the interview. However, YaoYao is so busy that he has no time to interview them by himself. So he decides…

人生中第一次写RMQ....一看就知道 RMQ+2分但是题目文不对题....不知道到底在问什么东西....各种WA,TLE,,RE...后就过了果然无论错成什么样都可以过的,就是 上层的样例 啊  Interviewe Time Limit: 2000/1000 MS (Java/Others)    Memory Limit: 65536/32768 K (Java/Others)Total Submission(s): 3865    Accepted Submission(s): 956…

题目大意:给定n个数的序列,让我们找前面k个区间的最大值之和,每个区间长度为n/k,如果有剩余的区间长度不足n/k则无视之.现在让我们找最小的k使得和严格大于m. 题解:二分k,然后求RMQ检验. ST算法: #include <cstdio> #include <algorithm> #include <cstring> using namespace std; const int maxn=200010; int d[maxn][30]; int a[maxn];…

RMQ问题小结 by Wine93 2014.1.14   1.算法简介 RMQ问题可分成以下2种 (1)静态RMQ:ST算法 一旦给定序列确定后就不在更新,只查询区间最大(小)值!这类问题可以用倍增的ST算法进行预处理 预处理:O(nlogn) 查询:O(1) (2)动态RMQ:线段树 要更新一些值,还有询问 更新:O(logn) 查询:O(logn) 2.相关题目 (1)静态RMQ 1.POJ 3264 Balanced Lineup(一维静态RMQ模板题) http://poj.org/p…
