Problem: 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.

Examples

Input

2 3
abc

Output

#####
#abc#
#arc#
#####


Input

1 1
z


Output

z#

Solution (in PYTHON):

Solution:
indata = raw_input().split()
i = int(indata[0])
j = int(indata[1])
pixcel = []

for count in range(i):
    datalist = raw_input()
    pixcel.append(datalist)

showline = []
headder = ""
l = ""

for x in range(j + 2):
    headder = headder + "#"
showline.append(headder)

for s in pixcel:
   l = "#" +  s + "#"
   showline.append(l)
showline.append(headder)

for line in showline:
    print line
