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.

Sample Input 1

2 3
abc
arc

Sample Output 1

#####
#abc#
#arc#

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>

int main(void)
{
  int H,W;
  char pic[300][300];
  char str[300];
  int i,j;

  scanf("%d %d",&H,&W);

  //printf("%d %d\n",H,W);

  for(i = -1;i < H;i++)
    {
      //printf("i = %d\n",i);
      gets(str);
      sscanf(str,"%s",pic[i]);
    }

  for(i = 0;i < W + 2;i++)
    printf("#");
  printf("\n");

  for(i = 0;i < H;i++)
    {
      printf("#");
      for(j = 0;j < W;j++)
        printf("%c",pic[i][j]);
      printf("#\n");
    }

  for(i = 0;i < W + 2;i++)
    printf("#");
  printf("\n");

  return 0;
}
