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

2 3
abc
arc


Output

#####
#abc#
#arc#

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();
        int w = sc.nextInt();

        String[] image = new String[h];
        for (int i = 0; i < h; i++) {
            image[i] = sc.next();
        }

        String wall = "##";
        for (int i = 0; i < w; i++) {
            wall += "#";
        }

        System.out.println(wall);
        for (int i = 0; i < h; i++) {
            image[i] = "#" + image[i] + "#";
            System.out.println(image[i]);
        }
        System.out.println(wall);
    }
}
