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 JAVA (judge verdict: Accepted)

import java.util.Scanner;
import java.lang.Math;

public class Main {
  public static void draw(int a, int b)
  {
    for (int i = 0; i < a; i++) {
      for (int j = 0; j < b; j++) {
        System.out.print("#");
      }
      System.out.println();
    }
  }
  public static void main(String[] args)
  {
    Scanner scan = new Scanner(System.in);
    while(true)
    {
      int a = scan.nextInt();
      int b = scan.nextInt();
      if(a ==0 && b == 0) break;
      draw(a,b);
      System.out.println();
    }
    scan.close();
  }
