描述 In the traditional RMQ (Range Minimum Query) problem, we have a static array A. Then for each query (L, R) (L<=R), we report the minimum value among A[L], A[L+1], …, A[R]. Note that the indices start from 1, i.e. the left-most element is A[1]. In…

题目大意 给定一个序列a[1],a[2]--a[n] 接下来给出m种操作,每种操作是以下形式的: l r d 表示把区间[l,r]内的每一个数都加上一个值d 之后有k个操作,每个操作是以下形式的: x y 表示把第x种操作一直到第y种操作都执行一遍 最终输出在k个操作结束之后的序列 题目大意 就是线段树的成段更新嘛~~~先用线段树统计每种操作的次数,然后再执行m次成段更新,最后查询到底的查询即可~~~树状数组也可搞,似乎写起来还更简单些~~~还有一个更犀利的O(n)的算法,不过我暂时还没弄懂~~…
