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 Fortran (gfortran v4.8.4) (judge verdict: Accepted)

program main
  implicit none
  integer :: h, w, i, j
  character(102) :: line
  character(1), allocatable :: tab(:, :)
  read(*, *) h, w
  allocate(tab(0:w + 1, 0:h + 1))
  tab(:, :) = "#"
  do i = 1, h
    read(*, *) line
    do j = 1, w
      tab(j, i) = line(j:j)
    end do
  end do
  do i = 0, h + 1
    do j = 0, w + 1
      line(j + 1:j + 1) = tab(j, i)
    end do
    write(*, "(a)") trim(line)
  end do
end program main
