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 {
  def main(args:Array[String]):Unit = {
    for (line <- scala.io.Source.stdin.getLines() if line != "0 0") {
      val Array(h, w) = line.split(" ").map(_.toInt)
      for (i <- 1 to h) {
        println("#" * w)
      }
      println()
    }
  }
