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.readLine

object Main extends App {

  for (_ <- 1 to 300) {
    val input = readLine.split(" ").map(_.toInt)
    val (h, w) = (input(0), input(1))

    if (h == 0 && w == 0) sys.exit() else {
      for (e <- 1 to h) {
        println("#" * w)
      }
      println()
    }
  }

}
