Problem: 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.

Examples

Input

Solution (in CPP):

Solution:
#include<string.h>
#include<stdio.h>

int main() {
	char z[103];
	int n, m, i, j;
	while(scanf("%d%d",&n,&m)!=EOF) {
		for(i=-2;i<m;i++) {
			printf("#");
		}
		printf("\n");
		for(j=0;j<n;j++) {
			scanf("%s",z);
			printf("#%s#\n",z);
		}
		for(i=-2;i<m;i++) {
			printf("#");
		}
		printf("\n");
	}
