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(void)
{
  int h, w;
  char s[101][101];
  scanf("%d %d", &h, &w);
  for (int i = 0; i <= h+1; i++) {
    for (int j = 0; j <= w+1; j++) {
      s[i][j] = '#';
    }
  }
  for (int i = 1; i <= h; i++) {
    scanf("%s", s[i]);
    for (int j = w; j > 0; j--) {
      s[i][j] = s[i][j-1];
    }
    s[i][0] = '#';
  }
  for (int i = 0; i <= h+1; i++) {
    for (int j = 0; j <= w+1; j++) {
      printf("%c", s[i][j]);
    }
    putchar('\n');
  }
