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

Solution in Scala (judge verdict: Accepted)

import scala.util.control.Breaks
object Main extends App {
  val b = new Breaks()
  b.breakable {
    while (true) {
      val Seq(h, w) = readLine().split(' ').map(_.toInt).toList

      if ((h, w) == (0, 0)) b.break

      println((("#" * w)  + '\n') * h)
    }
  }
