题目描述
The famous writer Velepin is very productive. Recently, he signed a contract with a well-known publication and now he needs to write ki books for i-th year. This is not a problem for him at all, he can write as much as he wants about samurai, space, emptiness, insects and werewolves.
He has n regular readers, each of whom in the i-th year will read one of the ki books published by Velepin. Readers are very fond of discussing books, so the j-th of them will be satisfied within a year if at least aj persons read the same book as him (including himself).
Velepin has obvious problems with marketing, so he turned to you! A well-known book reading service can control what each of Velepin's regular readers will read, but he does not want books to be wasted, so someone should read each book. And so they turned to you with a request to tell you what the maximum number of regular readers can be made satisfied during each of the years, if you can choose each person the book he will read.
著名作家维莱平非常高产。最近,他与一家知名出版机构签订了一份合同,现在他需要在第 i 年完成 ki 本书的写作。这对他而言完全不是问题——他可以随心所欲地创作关于武士、太空、虚空、昆虫以及狼人的作品。
他有 n 位固定读者,每位读者在第 i 年会从维莱平当年出版的 ki 本书中选择一本阅读。读者们非常热衷于讨论书籍,因此第 j 位读者在某一年内感到满意,当且仅当至少有 aj 人(包括他自己)阅读了与他相同的那本书。
维莱平在市场营销方面存在明显短板,于是他向你求助!一家知名的图书阅读服务平台能够控制每位固定读者所阅读的具体书籍;但维莱平不希望任何一本书被浪费,因此每本书都必须至少被一人阅读。于是他们请求你:在满足“每本书至少被一人阅读”的前提下,通过为每位读者指定其所读的书,求出每年最多能让多少位固定读者感到满意。
输入格式
The first line contains a single integer n (2≤n≤3⋅105) — the number of regular readers of Velepin.
The second line contains n integers a1,a2,…,an (1≤ai≤n) — the number of necessary readers of the same book for the happiness of the i-th person.
The third line contains a single integer q (1≤q≤3⋅105) — the number of years to analyze.
Each of the following q lines contains a single integer kj (2≤kj≤n) — the number of books that Velepin must write in j-th a year.
第一行包含一个整数 n(2≤n≤3⋅105)—— Velepin 的常规读者人数。
第二行包含 n 个整数 a1,a2,…,an(1≤ai≤n)—— 第 i 个人为获得幸福感所需共同阅读同一本书的读者人数。
第三行包含一个整数 q(1≤q≤3⋅105)—— 需要分析的年份数。
接下来的 q 行中,每行包含一个整数 kj(2≤kj≤n)—— Velepin 在第 j 年必须撰写的书本数量。
输出格式
Print q lines, each of them has exactly one number — the maximum number of people who can be satisfied in j-th a year if Velepin releases kj books.
输出 q 行,每行恰好一个数字——即若 Velepin 在第 j 年发布 kj 本书时,最多能满足的人数。

说明/提示
In the first example, in the first year, the optimal division is 1,2,2,2,2 (the first book is read by the first person, and everyone else reads the second). In the second year, the optimal solution is 1,2,2,3,3 (the first book is read by the first person, the second book is read by the second and third person, and all the others read the third book). In the third year, the optimal split will be 1,2,3,4,2. Accordingly, the number of satisfied people over the years will be 5,5,3.
In the second example, in the first year, the optimal division is 1,1,1,1,1,2, then everyone will be happy except the 6-th person. In the second year, the optimal division is 1,1,1,1,2,3, then everyone will be happy except the 5-th and 6-th person.
在第一个例子中,第一年最优的分配方案是 1,2,2,2,2(第一本书由第一个人阅读,其余所有人阅读第二本书);第二年最优的分配方案是 1,2,2,3,3(第一本书由第一个人阅读,第二本书由第二和第三个人阅读,其余所有人阅读第三本书);第三年最优的分配方案为 1,2,3,4,2。因此,各年满意人数分别为 5,5,3。
在第二个例子中,第一年最优的分配方案是 1,1,1,1,1,2,此时除第六个人外,其余人均满意;第二年最优的分配方案是 1,1,1,1,2,3,此时除第五和第六个人外,其余人均满意。
