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}

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

#include<stdio.h>

int main()
{
	int h,w,i;
	scanf("%d %d",&h,&w);

	char s[h][w];

	for (i=0; i < w+2; i++) {
		printf("#");
	}
	printf("\n");
	
	for (i=0; i<h; i++) {
		scanf("%s",s[i]);
		printf("#%s#\n",s[i]);
	}

	for (i=0; i<w+2; i++) {
		printf("#");
	}
	printf("\n");
	
	return 0;
