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

Solution (in CPP):

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

void up_down(int w) {
  for(int i=0;i<w+2;i++){
    cout<<'#';
  }
  cout<<endl;
}

int main() {
  int h, w;
  cin>>h>>w;
  up_down(w);
  for(int i=0;i<h;i++){
    string s;
    cin>>s;
    cout<<'#'<<s<<'#'<<endl;
  }
  up_down(w);
}
