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)

object Main extends App {
  val sc = new java.util.Scanner(System.in)
  print(sc.nextInt, sc.nextInt)

  def print(h: Int, w: Int): Unit = {
    (h, w) match {
      case (0, 0) => sc.close()
      case _ => {
        for (i <- 1 to h) {
          println("#" * w)
        }
        println()
        print(sc.nextInt(), sc.nextInt())
      }
    }
  }
