题目链接:http://www.lydsy.com/JudgeOnline/problem.php?id=3433 题意: 给出n个区间[a,b). 有两个记录器,每个记录器中存放的区间不能重叠. 求两个记录器中最多可放多少个区间. 题解: 贪心. 先按右端点从小到大排序. p1,p2分别为两个记录器的最右端. 始终令p1 < p2(避免出现大材小用). 对于每个区间s: if p1 <= s.l,则将s放入p1所在记录器.即:p1 = s.r, ans++; else if p2 <=…

题意:给出n个区间[a,b),有2个记录器,每个记录器中存放的区间不能重叠.求2个记录器中最多可放多少个区间. 解法:贪心.只有1个记录器的做法详见--关于贪心算法的经典问题(算法效率 or 动态规划).而对于2个,就是在1个的基础上(按 bi 排序,选第一个与之前没有相交的区间)维护2个值,注意要好好for循环遍历一次O(n),若想着用while直接跳过一些区间很容易出错!!!另外,遍历时要先考虑能否把当前的区间接在之前右端点较右的记录器. 1 #include<cstdio> 2 #inc…

大家是否有这种经验,“不知道为什么按出recording状态,按ESC貌似无法直接退掉”的情况,个人已经有过好几次了.与其出来烦人还不如了解它,昨天我就花了点时间学习recording.怎么说,还是有点用的.首先说明的是recording是怎么按出来的:命令模式下按q.假如你想按退出的:q,右手有点慢的话就有可能出现recording.顺便说一句,q:出来的是command history,command history状态下:q或者enter都可以退出.那么recording是干啥的?简单来说…
