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:

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.

#include<stdio.h>
int main()
{
	char a[102][102],i,j,h,w;
	scanf("%d%d",&h,&w);
     for(i=1;i<=h;i++)
		 scanf("%s",&a[i][1]);
	 for(i=0;i<w+2;i++)
	 {
		 a[0][i]='#';
		 a[h+1][i]='#';
	 }
	 for(i=0;i<h+2;i++)
	 {
		 a[i][0]='#';
		 a[i][w+1]='#';
	 }
	 for(i=0;i<=h+1;i++)
	 {
		 for(j=0;j<=w+1;j++)
			 printf("%c",a[i][j]);
		 printf("\n");
	 }
	 return 0;
