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

import java.util.*;

public class Main{
  public static void main(String[] args){
    Scanner sc=new Scanner(System.in);
    int h=sc.nextInt();
    int w=sc.nextInt();
    String[] a=new String[h];
    for(int i=0;i<h;i++){
      a[i]=sc.next();
    }
    for(int i=0;i<w+2;i++){
      System.out.print("#");
    }
    System.out.println("");//改行
    for(int i=0;i<h;i++){
      System.out.print("#");
      System.out.print(a[i]);
      System.out.println("#");
    }
    for(int i=0;i<w+2;i++){
      System.out.print("#");
    }
