N个数(N<=100000),M个询问,每次询问L,R,求F(L,R). F(L,R)=F(L,R-1)%A[R] , L<R 这道题数据比较鶸 可以直接用递减爆 正确做法应该是倍增 用倍增的思想,对于位置i右侧的最长下降子序列,next[i][j]表示位置i右边第2j个的位置,预处理出每个位置的next数组 每次做的时候尽量远跳,直到找到next[j][0]恰好小于当前的值z,则z对A[next[j][0]]取模,移动左标记,继续查找,直到超出R或者没有更小的数 // //by coolxx…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5884 题目大意:有n个有序的序列,对于第i个序列有ai个元素. 现在有一个程序每次能够归并k个序列, 他的花费为k个序列中的总的元素数.现在想知道在花费不超过t的情况下存在的最小的k为多少? 解题思路:二分k的值,合并k个序列的值, 加入队列,然后用哈夫曼检查最小花费是否超过t! 这时需要注意最后一次合并是否为k个数, 如果不是k个数,就不是最优的哈夫曼的值, 如果最后是k个数, 那么最后n, k一…
