http://poj.org/problem?id=3274 题意 :农夫约翰的n(1 <= N <= 100000)头奶牛,有很多相同之处,约翰已经将每一头奶牛的不同之处,归纳成了K种特性,比如1号特性代表它身上有斑点,2号特性代表它比较喜欢用passcal 写程序而不是C .约翰使用“特性标识符”来描述奶牛的各种特性,例如:一头奶牛的特性标识符是13,将13写成二进制1101,从右向左看,就表示这头奶牛具有1,3,4这三个特性,但没有2号特性,约翰把n头奶牛排成一排,发现在有些连续区间里的…

Farmer John's N cows (1 ≤ N ≤ 100,000) share many similarities. In fact, FJ has been able to narrow down the list of features shared by his cows to a list of only K different features (1 ≤ K ≤ 30). For example, cows exhibiting feature #1 might have s…

我早期在csdn的博客之一,正好复习st表就拿过来.http://write.blog.csdn.net/mdeditor#!postId=63713810 这道题其实本身不难(前提是你得掌握线段树或者st表当中的一种) 那么这道题我们来讲一讲st表(因为这题询问次数有点多) 一般关系式 dp[i][j]=min/max(dp[dp[i][j-1],dp[i+pow(2,j-1)][j-1]]) 可以看出来吧,其实这就是动态规划 好的我们来解释一下关系式是什么吧 首先这个是一个二分,具体是什么呢…
