题目描述
The only difference between easy and hard versions is the maximum values of $n$ and $q$ .
You are given an array, consisting of $n$ integers. Initially, all elements are red.
You can apply the following operation to the array multiple times. During the $i$ -th operation, you select an element of the array; then:
- if the element is red, it increases by $i$ and becomes blue;
- if the element is blue, it decreases by $i$ and becomes red.
The operations are numbered from $1$ , i. e. during the first operation some element is changed by $1$ and so on.
You are asked $q$ queries of the following form:
- given an integer $k$ , what can the largest minimum in the array be if you apply exactly $k$ operations to it?
Note that the operations don't affect the array between queries, all queries are asked on the initial array $a$ .

输入格式
The first line contains two integers $n$ and $q$ ( $1 \le n, q \le 1000$ ) — the number of elements in the array and the number of queries.
The second line contains $n$ integers $a_1, a_2, \dots, a_n$ ( $1 \le a_i \le 10^9$ ).
The third line contains $q$ integers $k_1, k_2, \dots, k_q$ ( $1 \le k_j \le 10^9$ ).
The second line contains $n$ integers $a_1, a_2, \dots, a_n$ ( $1 \le a_i \le 10^9$ ).
The third line contains $q$ integers $k_1, k_2, \dots, k_q$ ( $1 \le k_j \le 10^9$ ).
输出格式
For each query, print a single integer — the largest minimum that the array can have after you apply exactly $k$ operations to it.
