CodeforcesRound#225(Div.1)C树状数组||线段树_html/css_WEB-ITnose

看到这题很开心啊,有印象跟以前做过的很像,貌似最近就做过一个,以时间戳为区间来建立树状数组,然后一开始我以为题意是,给x点加val,它以下的所有节点都加-val;所以一开始就以 加 和 减 建立了两个树状数组,最后 减去就是答案,写完发现跟案例对不上啊,读了题目也没发现读错了,对于那句话 我理解错了,后来看了 这个: http://blog.csdn.net/keshuai19940722/article/details/18967661 仔细看看处理部分,我还以为分奇...

CodeforcesRound#279(Div.2)F.TreelandTour(lis+dfs)_html/css_WEB-ITnose

题目链接: huangjing 题意:告诉一个无向无环图,然后求在联通的路上的lis。 思路:枚举起点求lis 复杂度是n^2logn,貌似这复杂度对时间有点玄,估计是数据有点弱。。。 首先枚举起点,然后求lis,主要是用dfs求的,要用到回溯的思想,我觉得是只要更新了,就要保存那个操作,然后一旦这一次的搜索完成,那么就要立即回复g数组的值,因为有很多不同的路线,所以一条路走完后,就要回复以前的状态哦,免得影响另外一条路。。...
