Pussycat Sonya has a string S of length N. And she's asked Q queries of form: What is the minimal number of circular shifts in left direction of string S she needs to perform to get lexicographically smallest string, if she can do Ki such shifts at most?

Input:
The first line of input contains one integer N - the length of the string S.
The second line contains string S.
The third line contains one integer Q - the number of queries.
Each of the next Q lines contains one integer Ki.

Output:
Print the answers for all queries.

Constraints:
1 ≤ N, Q ≤ 106
0 ≤ Ki < N

Explanation

Let's take a look at all circular shifts in left direction of string "pussycat":
0: "pussycat"
1: "ussycatp"
2: "ssycatpu"
3: "sycatpus"
4: "ycatpuss"
5: "catpussy"
6: "atpussyc"
7: "tpussyca"
We need exactly i operations to get i-th shift.

And now let's sort them lexicographically:
6: "atpussyc"
5: "catpussy"
0: "pussycat"
2: "ssycatpu"
3: "sycatpus"
7: "tpussyca"
1: "ussycatp"
4: "ycatpuss"
