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

2 3

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;

int main() {
	int h, w, i, j;
	cin >> h >> w;
	vector<string> a(h), b(h+2, string(w+2, '#'));
	
	for (i = 0; i < h; i++) {
		cin >> a.at(i);
		b[i + 1] = "#" + a[i] + "#";
	}
	for (i = 0; i < h + 2; i++) {
		cout << b[i] << endl;
	}
	return 0;
}
