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

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a = 1, b = 1;
        while (true) {
            a = scanner.nextInt();
            b = scanner.nextInt();
while (a != 0 && b != 0) {
            for (int i = 1; i <= a; i++) {
                for (int j = 1; j <= b - 1; j++) {
                    System.out.print("#");
                }
                System.out.println("#");
            }
            System.out.println("");
