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>
#include <stdlib.h>

int main()
{
	int H,W,i,j=0,m,n,k;
	char s[120][120],a[120];
    for (i=0;i<=105;i++)
	for (k=0;k<=105;k++)
	s[i][k]='#';
	scanf ("%d%d",&H,&W);
	getchar();
    for (m=1;m<=H;m++)
    {
        gets(a);
        j++;
        for (k=1;k<=W;k++)
        s[j][k]=a[k-1];
    }
    for (j=0;j<H+2;j++)
    {
        for (i=0;i<=W+1;i++)
        printf("%c",s[j][i]);
        printf("\n");
    }
