Input

The input consists of multiple datasets. Each dataset consists of two integers H and W separated by a single space.

The input ends with two 0 (when both H and W are zero).

Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

Solution in Ruby (judge verdict: Accepted)

loop{
  h, w = STDIN.gets.split.map(&:to_i)
  break if h == 0 && w == 0

  w_arr = Array.new(w)
  h_arr = Array.new(h)
  w_arr.fill('#')
  h_arr.fill(w_arr.join)
  puts h_arr.join("\n")
  puts
}
