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()

{
    int i,j,a,b,c,d,n,m;
    scanf("%d",&m);
    scanf("%d ",&n);
    char ar[m+2][n+2];
    for(i=0;i<m+2;i++)
    {
      for(j=0;j<n+2;j++)
      {
          ar[i][j]='#';
      }
    }
 
     for(a=1;a<=m;a++)
    {
      for(b=1;b<=n;b++)
      {
          if(b==n && a!=m)
            scanf("%c ",&ar[a][b]);
          else
            scanf("%c",&ar[a][b]);
