Can you answer these queries? HDU-4027 题目链接 题目大意是一个长度为 N (N<=1e5)的区间,区间里元素都是正整数,现在有M(M<=1e5)次区间修改与查询,区间修改的操作L,R会将[L,R]区间里面的所有元素开方(向下取整),区间查询会询问[L,R]的区间和,保证区间和小于 2^63,多组样例输入。 开始拿到这个题思...
Can you answer these queries? (线段树 题目 题意: 初始给你n个数,通过m个操作, 操作0是使区间范围内的每一个a[i]都变成 根号a[i] ,操作1是查询区间范围内数字的和。 思路: 如果一个节点sum[rt]是1的话,根号1还是1,重复遍历这个节点会大大增加计算次数。n和区间左右端点的范围都 <=1e5,所以一个节点...
思路:表面上是区间更新,但是每个数开方这种操作区间更新的慵懒标记难以做到,所以这个题不用慵懒标记,而是直接采用 单节点更新的思想,但是单节点更新一定会超时,所以做一个剪枝:当当前区间的值全为1时直接return,不进行任何更新,这是显然的,1开方还是1,更新的话只会徒增复杂度,其他的按照一般的模板写就可以了 #incl...

链接:https://vjudge.net/contest/260644#problem/H 思路:我们考虑1e18内的数据可以在常数次以内开根号变为1,所以我们维护区间信息时考虑维护区间最大值,如果区间最大值为1的话那么当前区间所有值都为1不用再递归,否则递归左右子树一直到叶节点或者到区间最大值为1的地方,在叶节点更新值,同时pushup回去合并区间...

As @AndreKR shows in his answer. MIN() and MAX() don't affect the where statement. I'm not entirely sure what you're trying to do ... Why are you only looking at the first and last 15 rows. If you're trying to get the last value used by auto_incremen...
