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.io.PrintWriter;
import java.util.Scanner;

class Main{
    private static final Scanner sc = new Scanner(System.in);
    private static final PrintWriter out = new PrintWriter(System.out);
    public static void main(String[] Args){
        while(true){
            final int h = Integer.parseInt(sc.next());
            final int w = Integer.parseInt(sc.next());
            if(h==0&&w==0) break;
            for(int i = 0; i<h; i++){
                for(int j = 0; j<w; j++){
                    out.print("#");
                }
                out.println();
            }
            out.println();
        }
        out.flush();
    }
