[BZOJ2482][Spoj1557] Can you answer these queries II Description 给定n个元素的序列. 给出m个询问:求l[i]~r[i]的最大子段和(可选空子段). 这个最大子段和有点特殊:一个数字在一段中出现了两次只算一次. 比如:1,2,3,2,2,2出现了3次,但只算一次,于是这个序列的和是1+2+3=6. Input 第一行一个数n. 第二行n个数,为给定的序列,这些数的绝对值小于等于100000. 第三行一个数m. 接下来m行,每行两个…

GSS7 Can you answer these queries IV 题目:给出一个数列,原数列和值不超过1e18,有两种操作: 0 x y:修改区间[x,y]所有数开方后向下调整至最近的整数 1 x y:询问区间[x,y]的和 分析: 昨天初看时没什么想法,于是留了个坑.终于在今天补上了. 既然给出了1e18这个条件,那么有什么用呢?于是想到了今年多校一题线段树区间操作时,根据一些性质能直接下沉到每个节点,这里可以吗?考虑1e18开方6次就下降到1了,因此每个节点最多被修改6次.于是我们每…

传送门 解题思路 大概就是一个数很少次数的开方会开到\(1\),而\(1\)开方还是\(1\),所以维护一个和,维护一个开方标记,维护一个区间是否全部为\(1/0\)的标记.然后每次修改时先看是否有全\(1\)或\(0\)的标记,有就不用理了,没有就暴力开方. 代码 #include<iostream> #include<cstdio> #include<cstring> #include<cmath> #define int long long using…
