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)

object Main {
    import scala.annotation.tailrec

    def main(args: Array[String]) = {
        val sc = new java.util.Scanner(System.in)

        drawRectangle(sc)
    }

    @tailrec
    def drawRectangle(scanner: java.util.Scanner): Unit = {
        val h, w = scanner.nextInt

        if( h != 0 || w != 0 ) {
            for( i <- 0 until h ) println("#"*w)
            print("\n")
            drawRectangle(scanner)
        }
    }
