Problem Statement

There are N squares arranged in a row, numbered 1, 2, ..., N from left to right.
You are given a string S of length N consisting of . and #. If the i-th character of S is #, Square i contains a rock; if the i-th character of S is ., Square i is empty.

In the beginning, Snuke stands on Square A, and Fnuke stands on Square B.

You can repeat the following operation any number of times:

Choose Snuke or Fnuke, and make him jump one or two squares to the right. The destination must be one of the squares, and it must not contain a rock or the other person.

You want to repeat this operation so that Snuke will stand on Square C and Fnuke will stand on Square D.

Determine whether this is possible.

Constraints

4 \leq N \leq 200\ 000

S is a string of length N consisting of . and #.

1 \leq A, B, C, D \leq N

Square A, B, C and D do not contain a rock.

A, B, C and D are all different.

A < B

A < C

B < D

Input

Input is given from Standard Input in the following format:

N A B C D
S

Output

Print Yes if the objective is achievable, and No if it is not.

Sample Input 1

7 1 3 6 7
.#..#..

Sample Output 1

Yes

The objective is achievable by, for example, moving the two persons as follows. (A and B represent Snuke and Fnuke, respectively.)

A#B.#..

A#.B#..

.#AB#..

.#A.#B.

.#.A#B.

.#.A#.B

.#..#AB

Sample Input 2

7 1 3 7 6
.#..#..

Sample Output 2

No

Sample Input 3

15 1 3 15 13
...#.#...#.#...

Sample Output 3

Yes

Solution in Ruby (2.3.3) (judge verdict: Accepted)

n,a,b,c,d = gets.chomp.split(' ').map(&:to_i)
s = gets.chomp

# 連続岩 = false
追い抜く必要性 = c > d
# 追い抜ける = false
連続岩 = s[(a-1)..(([c,d].max)-1)].include?('##')
if 追い抜く必要性
  追い抜ける = s[(b-2)..d].include?('...')
end
# s.split('').each_with_index do |char, i|
#   x = i + 1
#   if x > a && (x < c || x < d)
#     if char == '#' && s[i-1] == '#'
#       連続岩 = true
#       break
#     end
#   end
# 
#   if 追い抜く必要性 && x > b && x <= d
#     if char == '.' && s[i-1] == '.' && s[i-2] == '.'
#       追い抜ける = true
#     end
#   end
# end

if 連続岩
  puts 'No'
  exit
end

if 追い抜く必要性
  unless 追い抜ける
    puts 'No'
    exit
  end
end

puts 'Yes'
