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 JAVA (judge verdict: Wrong Answer)

import java.util.*;
import java.io.*;

public class Main{
    public static void main(String[] args)throws IOException{
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    
    int a = 1;
    int b = 1;
    
    
        while(true){
            StringTokenizer st = new StringTokenizer(br.readLine(), " ");
            a = Integer.parseInt(st.nextToken());
            b = Integer.parseInt(st.nextToken());

            if(a==0&&b==0)break;
            for(int x = 0; x<b; x++){
                
                
                for(int y = 0; y<a; y++){
                    System.out.print("#");
                }
                
                System.out.print("\n");
