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.

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

#include <stdio.h>

int main (void){

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

	int i, j;
	char a[1000][1000];

 	for(i = 0; i < H; i++){
   		scanf("%s", a[i]);  
 	}
	
	char b[1000][1000];

	for(i = 0; i < H + 2; i++){
                for(j = 0; j < W + 2; j++){
                        b[i][j] = '#';
                }
        }

	for(i = 1; i < H + 1; i++){
                for(j = 1; j < W + 1; j++){
                        
			b[i][j] = a[i - 1][j - 1];
                }
        }	

	for(i = 0; i < H + 2; i++){
  		 printf("%s\n", b[i]);  
 	}	

	return 0;
