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

        Scanner sc = new Scanner(System.in);

        while(true){
            int h = sc.nextInt();
            int w = sc.nextInt();
    
            for(int i = 0;i<h;i++){
                for(int j = 0;j<w;j++){
                    System.out.printf("#");
                }
                System.out.println();
            }
            System.out.println();
            if(h==0 && w==0) break;
        }
