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.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
 
public class Main {
    public static void main(String args[]) throws IOException{
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        StringBuilder builder = new StringBuilder();
        while(true){
            String data[] = reader.readLine().split(" ");
            int a= Integer.parseInt(data[0]);
            int b= Integer.parseInt(data[1]);
             
            if(a==0 && b==0)
                break;
             
            for(int y=0; y<a; y++){
                for(int x=0; x<b; x++){
                    builder.append("#");
