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

2 3
abc

Sample Output 1

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

Sample Input 2

1 1
z

Sample Output 2

#include <stdio.h>
	int main(void) {
		int h, w, i;
		scanf("%d %d", &h, &w);
		if(h<1 || h>100 || w<1 || w>100){
			return 1;
		}
		char *p[h];
		for(i=0; i<h; i++){
			scanf("%s",p[i]);
			/*if(strlen(p[i]) != w){
				return 1;
			}*/
		}
		for(i=0; i<w+2; i++){
			printf("#");
		}
		for(i=0; i<h; i++){
			printf("\n");
			printf("#");
			printf("%s",p[i]);
			printf("#");
		}
		printf("\n");
		for(i=0; i<w+2; i++){
			printf("#");
		}
		return 0;
