Problem Statement

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:

import java.util.*;

class Main {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int hight = sc.nextInt();
        int width = sc.nextInt();

        String[] pic = new String[hight];

        for (int i = 0; i < hight; i++) {
            // System.out.println("DEBUG i:" + i);
            pic[i] = sc.next();
        }

        // System.out.println("DEBUG:" + pic);

        for (int i = 0; i < width + 2; i++) {
            System.out.print("#");
        }

        System.out.println();

        for (int i = 0; i < hight; i++) {
            System.out.print("#");

            System.out.print(pic[i]);

            System.out.println("#");
        }

        for (int i = 0; i < width + 2; i++) {
            System.out.print("#");
        }

        System.out.println();

    }
