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 Python (3.4.3) (judge verdict: Wrong Answer)

n,a,b,c,d = (x-1 for x in map(int,input().split()))
n+=1
s = input()

if "##" in s[b:d+1]:
	# print('b-dで岩２つ')
	ans = 'No'
else:
	if "##" in s[a:c+1]:
		# print('a-cで岩２つ')
		ans = 'No'
	else:#邪魔な岩は無し
		if c>d: #ふぬけを飛び越える必要がある場合
			#ふぬけ君を飛び超えるために3マス以上連続で空いてる場所を探してあげる
			if "..." in s[b:d]:
				# print('空きマス３つある')
				ans = 'Yes'
			else:#飛び越えるスペースが無かった
				# print(s[b:])
				# print('空きマス３つない・・・')
				ans = 'No'
		else:#ふぬけ、すぬけの順に動かせばいい場合、岩はもう見た
			# print('ふぬけ→すぬけ　OK')
			ans = 'Yes'

print(ans)
