Problem: 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.

Examples

Input

2 3
abc
arc


Output

#####
#abc#
#arc#
#####


Input

1 1
z


Output

Solution (in CPP):

Solution:
#include  <stdio.h>
int main(void){
  int h,w,i;
  char t[100];
  scanf("%d%d\n",&h,&w);
  for (i=0;i<w+2;i++) printf("#");
  printf("\n");
  for (i=0;i<h;i++){
    scanf("%s",t);
    printf("#%s#\n",t);
  }
  for (i=0;i<w+2;i++) printf("#");
  printf("\n");
  return 0;
}
