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

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

#include <stdio.h>

int main(void)
{
  int i, j, h, w;
  char img[102][102];

  for (i = 0; i < 102; i++) {
    for (j = 0; j < 102; j++) {
      img[i][j] = '#';
    }
  }

  scanf("%d %d%*c", &h, &w);

  for (i = 1; i < h + 1; i++) {
    for (j = 1; j < w + 1; j++) {
      scanf("%c", &img[i][j]);
    }
    getchar();
  }

  for (i = 0; i < h + 2; i++) {
    for (j = 0; j < w + 2; j++) {
      putchar(img[i][j]);
    }
    putchar('\n');
  }

  return 0;
