题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=6315 题目大意:告诉你a,b两个数组,a数组初始化为0,b数组告诉你长度和具体值,接下来有q次操作,add操作是从向区间[l,r]加1,query操作是求区[l,r]的ai/bi的总和. 解题思路:维护一个mn,表示这个区间里的a最少加几次才能有新的贡献.比如1最多对总和造成q的贡献,2最多q/2,q/3,q/4,一直到q/n.最少要加min(b[i]-a[i]%b[i])次才能有新的贡献,如果这个…

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>…
