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 S of length N and an integer k (k \geq 3),
he defines the k-DMC number of S as the number of triples (a, b, c) of integers that satisfy the following conditions:

0 \leq a < b < c \leq N - 1

S[a] = D

S[b] = M

S[c] = C

c-a < k

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

For a string S and Q integers k_0, k_1, ..., k_{Q-1}, calculate the k_i-DMC number of S for each i (0 \leq i \leq Q-1).

Constraints

3 \leq N \leq 10^6

S consists of uppercase English letters

1 \leq Q \leq 75

3 \leq k_i \leq N

All numbers given in input are integers

Input

Input is given from Standard Input in the following format:

N
S
Q
k_{0} k_{1} ... k_{Q-1}

Output

Print Q lines.
The i-th line should contain the k_i-DMC number of the string S.

Sample Output 1

(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\times 5\times 7.

(a, b, c) = (0, 23, 36), (8, 23, 36) satisfy the conditions except the last one, namely, c-a < k_i.

By the way, DWANGO is an acronym for "Dial-up Wide Area Network Gaming Operation".

Solution in Ruby (2.3.3) (judge verdict: Time Limit Exceeded)

n1 = gets.to_i
wo = gets.chomp.split("")
n2 = gets.to_i
n3 = gets.chomp.split(" ").map(&:to_i)
d = Array.new(n1, 0)
m = Array.new(n1, 0)
c = Array.new(n1, 0)

for i in 0..n1 - 1
  if wo[i] == "D"
    d[i] += 1
  elsif wo[i] == "M"
    m[i] += 1
  elsif wo[i] == "C"
    c[i] += 1
  end
end

for i in 0..n2 - 1
  ans = 0
  for j in 0..n1 - 1
    if wo[j] == "D"
      inst = 0
      for k in 1..n3[i] - 1
        if wo[j + k] == "M"
          inst += 1
        elsif wo[j + k] == "C"
          ans += inst
        end
      end
    end
  end
  puts ans
end
