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}
:

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
int main(){
  int h,w,i,j;
  char a[101][101];
  
  scanf("%d %d",&h,&w);
  for(i=0;i<h;i++){
    scanf("%s",a[i]);
  }
  
  for(i=0;i<h+2;i++){
    for(j=0;j<w+2;j++){
      if(i==0 || j==0 || i==(h+1) || j==(w+1)){
        printf("#");
      } else {
        printf("%c",a[i-1][j-1]);
      }
    }
    printf("\n");
  }
}
