Solution in Ruby (judge verdict: Accepted)

while true do
  num=Array.new
  str=gets.chomp
  number=str.split
  num[0]=number[0].to_i
  num[1]=number[1].to_i
  if num[0]==0 && num[1]==0 then
    break
  end
  for i in 1..num[0] do
    for j in 1..num[1] do
      print "#"
    end
    print "\n"
  end
  print "\n"
end
