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.

Sample Input 1

2 3
abc
arc

Sample Output 1

#####
#abc#
#arc#

int main(){
  char *pic;
  int H,W;

  scanf("%d %d",&H,&W);
  pic=(char *)malloc(sizeof(char)*(H+2)*(W+2));
  buf=(char *)malloc(sizeof(char)*W+1);
  
  if(pic==NULL){
    printf("error");
    exit(0);
  }
  for(i=0;i<(H+2)*(W+2);i++){
    pic[i]='#';

    scanf("%s",buf);
    for(j=0;j<W;j++){
      pic[i*(W+2)+j+1]=buf[j];
    }
  }
  /*  for(i=0;i<(H+2)*(W+2);i++){

    printf("%c",pic[i]);
    if(i%(W+2)==W+1){
      printf("\n");
