【HDU】4960 Another OCD Patient 【DP】

传送门:【HDU】4960 Another OCD Patient 题目分析:比赛的时候写的太乱了,本来不需要合并的地方也合并了,现在重新改了改倒是清爽多了,顺便贴一下。 由于题目需要我们将原数组变成回文串,所以我们可以一开始就将原数组中必须合并的先合并了。那么什么是必须合并的呢?注意到左右对称,所以我们可以将左端的数相加正好等于右端的左右两个块分别合并(一定这样得到的是极小块),怎么相

UESTC 360(1425) another LCIS

这道题是CD老OJ上面的一道题,现在在新OJ上的题号是360,开始在VJ上做的提交一直RE(囧)。后来才知道OJ移位了。 这道题是一个简单的成段更新+区间合并的线段树的题,1A还让我小激动了一下 这道题的大概意思是有两种操作,一种是成段地增加一个值,另外一种是询问从l到r这段区间内的最长递增子序列 首先先分析一下,如果某一段的值成段地增加一个量,那么该区间内的数的相对大小是不变的,因此递增子
