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: WA: Presentation Error)

object Main {
  def main(args:Array[String]){
    val sc=new java.util.Scanner(System.in)
    var tmp=false
    println()
      while(true){
       val h,w=sc.nextInt
       if(h==0&&w==0) return
       if(tmp) println()
       for(i<-1 to h;j<-1 to w){
         if(j==w) println("#")
         else print("#")
       }
       tmp=true
     }
  }
