Problem:
Score : 400 points

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

    val sc = Scanner(System.`in`)
    val n = sc.nextInt()
    val a = sc.nextInt()
    val b = sc.nextInt()
    val c = sc.nextInt()
    val d = sc.nextInt()
    val s = sc.next()
    println(problem034a(n, a, b, c, d, s))
}

fun problem034a(n: Int, a: Int, b: Int, c: Int, d: Int, s: String): String {
    val canSunuke = (!"#{2,}?".toRegex().containsMatchIn(s.take(c).drop(a)))
    val canFunuke = (!"#{2,}?".toRegex().containsMatchIn(s.take(d).drop(b)))
    val canReplace = if (c > d) {
        val sub = s.take(d + 1).drop(b - 1)
        ("x{3,}?".toRegex().containsMatchIn(sub.replace(".", "x")))
    } else {
        true
    }
    return if (canFunuke && canSunuke && canReplace) "Yes" else "No"
