Problem:
Print a Rectangle

Draw a rectangle which has a height of H cm and a width of W cm. Draw a 1-cm square by single '#'.

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

1 ≤ H ≤ 300

1 ≤ W ≤ 300

Sample Input

Solution in Scala (judge verdict: Accepted)

import scala.io.StdIn

object Main extends App {

  var hw = StdIn.readLine().split(' ').map(_.toInt)
  while(hw(0) != 0 && hw(1) != 0){
    (0 until hw(0)).foreach{ _ =>
      (0 until hw(1)).foreach( _ => print("#"))
      println("")
    }
    println("")
    hw = StdIn.readLine().split(' ').map(_.toInt)
  }

}
