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 matrix1[110][110]={0}, matrix2[110][110]={0};;

	scanf("%d %d", &h, &w );
	
	for(i=0; i<h; i++){
	    for(j=0; j<w; j++){
	        scanf(" %c", &matrix1[i][j] );
	        
	        
	        
	    }
	    
	    
	}
	
	for(i=0; i<w+2; i++) printf("#");
	printf("\n");
	for(i=0; i<h; i++){
	    printf("#");
	    for(j=0; j<w; j++){
	        printf("%c", matrix1[i][j]);
	       
	    }
	    printf("#");
	    printf("\n");
	    
	}
	for(i=0; i<w+2; i++) printf("#");
	
	return 0;
