Solution in Ruby (2.3.3) (judge verdict: Wrong Answer)

a,b=gets.split(" ").map(&:to_i) ## 1 2を打つ
#puts a 　中身は1
#puts b   中身は2
a.times{
  $str = []
  key = gets.chomp
  $str.push(key)
}
b = b + 2
b.times{ print("#") }
puts("")
a.times do |i|
  print ("#")
  print $str[i]
  print ("#\n")
end
b.times{
  print("#")
}
