Problem: You are given a image with a height of H pixels and a width of W pixels. Each pixel is represented by a lowercase English letter. The pixel at the i-th row from the top and j-th column from the left is a_{ij}.

Put a box around this image and output the result. The box should consist of `#` and have a thickness of 1.

Constraints

* 1 ≤ H, W ≤ 100
* a_{ij} is a lowercase English letter.

Input

Input is given from Standard Input in the following format:


H W
a_{11} ... a_{1W}
:
a_{H1} ... a_{HW}


Output

Print the image surrounded by a box that consists of `#` and has a thickness of 1.

Examples

Input

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int h = sc.nextInt(),w = sc.nextInt();
		StringBuilder sb = new StringBuilder();
		sb.append(rep("#",w+2));
		sb.append("\n");
		for (int i = 0; i < h; i++) {
			sb.append("#");
			sb.append(sc.next());
			sb.append("#\n");
		}
		sb.append(rep("#",w+2));
		sb.append("\n");
		System.out.println(new String(sb));
		sc.close();
	}

	public static String rep(String s,int n) {
		StringBuilder sb = new StringBuilder();
		for (int i = 0; i < n; i++) {
			sb.append(s);
		}
		return new String(sb);
	}
}
