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

import java.util.Scanner;
import java.util.Arrays;
public class Main {
    public static void main(String[] args) throws Exception {
        Scanner sc = new Scanner(System.in);
        int x=1,y=1;
        while(x != 0 || y != 0){
            y = sc.nextInt();
            x = sc.nextInt();
            if (x == 0 && y == 0) break;
            for(int i=0;i<y;i++){
                for(int j=0;j<x;j++){
                    System.out.print('#');
                }
                System.out.println();
            }
            System.out.println();
        }
        
        sc.close();
