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: Wrong Answer)

#include <stdio.h>

int  main(void)
{
	int H,W;
	
	scanf("%d%d",&H,&W);
	
	char a[H][W];
	for(int i=0;i<H;i++){
		
			scanf("%s",&(a[i]));
		
	}
	/*
	for(int i=0;i<H;i++){
		for(int j=0;j<W;j++){
			scanf("%c",&(a[i][j]));
		}
	}
	
	for(int i=0;i<H;i++){
		for(int j=0;j<W;j++){
			printf("%c",(a[i][j]));
		}
			printf("\n");
	}
	*/
	for(int i=0;i<W+2;i++){
		printf("#");
	}
	
	printf("\n");
	
	for(int i=0;i<H;i++){
		printf("#");
		for(int j=0;j<W;j++){

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