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]);
  scanf("%s",a[0]);
  scanf("%s",a[1]);


  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("%c",a[i][j]);
    }
    printf("#\n");
  }
  for(int i = 0;i< W+2;i++) printf("#");
  printf("\n");

  return 0;
}
