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>
#include <stdlib.h>

int print(int p){
  for(int i = 0; i < p; i++){
     printf("#");
     }
    printf("\n");
    return 0;
   }
  

int main(void){

  int H = 0;
  int W = 0;
  int pic_yoko = 0;        //実際に表示するときの横のピクセル
  char  picture[101][101]; //二重配列
 
  scanf("%d %d", &H, &W);
  
  pic_yoko = W + 2;
 
  for(int i = 0; i < H; i++) {
    scanf("%s", &picture[i][0]);
  }
 
  print(pic_yoko); // 上から１行目
  
  for(int i = 0; i < H; i++) {
    printf("#%s#\n", picture[i]);
  }
  
  print(pic_yoko); // 一番下の行
 
  return 0;
}
