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.

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

#include <stdio.h>

int main (void)
{
  int h , m;
  scanf("%d %d",&h,&m);
  
  char a[h][m];
  
  for(int i = 0;i < m+2;i++){
    printf("#");
  }
  putchar('\n');
  
  for(int i = 0;i < h;i ++){
  scanf("%s",&a[i]);
  printf("#");
  printf("%s",a[i]);
  printf("#\n");
  }
  
  for(int i = 0;i < m+2;i++){
    printf("#");
  }
  
  return 0;
}
