Problem Statement

In Dwango Co., Ltd., there is a content distribution system named 'Dwango Media Cluster', and it is called 'DMC' for short. The name 'DMC' sounds cool for Niwango-kun, so he starts to define DMC-ness of a string.

Given a string SS of length NN and an integer kk (k3)(k \geq 3), he defines the k-DMC number of SS as the number of triples (a,b,c)(a, b, c) of integers that satisfy the following conditions:

  • 0a<b<cN10 \leq a < b < c \leq N - 1
  • S[a]S[a] = D
  • S[b]S[b] = M
  • S[c]S[c] = C
  • ca<kc-a < k

Here S[a]S[a] is the aa-th character of the string SS. Indexing is zero-based, that is, 0aN10 \leq a \leq N - 1 holds.

For a string SS and QQ integers k0,k1,...,kQ1k_0, k_1, ..., k_{Q-1}, calculate the kik_i-DMC number of SS for each ii (0iQ1)(0 \leq i \leq Q-1).

Constraints

  • 3N1063 \leq N \leq 10^6
  • SS consists of uppercase English letters
  • 1Q751 \leq Q \leq 75
  • 3kiN3 \leq k_i \leq N
  • All numbers given in input are integers

Input

Input is given from Standard Input in the following format:

NN

SS

QQ

k0k_{0} k1k_{1} ...... kQ1k_{Q-1}

Output

Print QQ lines. The ii-th line should contain the kik_i-DMC number of the string SS.

(a,b,c)=(0,6,11)(a,b,c) = (0, 6, 11) satisfies the conditions. Strangely, Dwango Media Cluster does not have so much DMC-ness by his definition.

The number of triples can be calculated as 6×5×76\times 5\times 7.

(a,b,c)=(0,23,36),(8,23,36)(a, b, c) = (0, 23, 36), (8, 23, 36) satisfy the conditions except the last one, namely, ca<kic-a < k_i. By the way, DWANGO is an acronym for "Dial-up Wide Area Network Gaming Operation".
