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: WA: Presentation Error)

object Main {
  def main(args: Array[String]): Unit = {
    val sc = new java.util.Scanner(System.in)
    
    def printRect(w:Int, h:Int):Unit = {
      if(w==0&&h==0){}
      else {
        for( i <- 1 to h) {
          println("#"*w)
        }
        printRect(sc.nextInt,sc.nextInt)
      }
    }

    printRect(sc.nextInt,sc.nextInt)

  }
