>>点击进入原题测试<< 思路:好像是第一次这么印象深刻的写线段树,说实话,这个题确实很有意思,值得学习. 看了大神讲解视频,但是自己写的还是超时了. 参考来自 https://blog.csdn.net/yiqzq/article/details/81211652 个人认为可以作为模板 #include <bits/stdc++.h> #include <iostream> #include <cstdio> #include <algo…

题目大意 题目链接Naive Operations 题目大意: 区间加1(在a数组中) 区间求ai/bi的和 ai初值全部为0,bi给出,且为n的排列,多组数据(<=5),n,q<=1e5 axmorz 思路 因为是整除,所以一次加法可以对ans 没有影响 当ai是bi的倍数,对ans会有贡献 所以我们维护一个sum,初值为bi(只对于线段树的叶子节点有用) 当区间+1的时候 我们对sum-1 当sum=0的时候(倍数) ans++,sum=bi 然后再维护一个区间最小值 当区间内的mi>…
